Sarah Palin has slammed Instagram as biased against conservatives after the company removed a controversial image she posted which used her own son with Down Syndrome to mock liberal protesters.

Palin posted the meme to her Instagram page on Tuesday, and the company removed it on Friday for violating 'community guidelines' after intense outcry over the image.

The image showed heroic female warriors with the label 'What protestors [sic] think we see', contrasted with pictures of Palin's 10-year-old son Trig melting down with the label 'What we really see'.

In a new post on Friday, Palin shared the takedown notice from Instagram and excoriated the company and parent firm Facebook in a lengthy diatribe accusing them of censorship and political bias.

Palin posted this takedown notice on Friday along with a lengthy caption blasting Instagram and parent company Facebook for alleged censorship and political bias

'CENSORSHIP is to sharing opinions as LYNCHING is to justice! Unbelievable. Instagram took down a post of my son Trig acting like a normal kid ~ which I am so proud he can do,' Palin wrote.

'My heart soars when Trig proves he’s a “normal” kid... I can’t even explain how it tickles our whole family. But the intolerant powers-that-be, sitting in a seat of judgement, think not?

'The nauseating, downright evil hypocrisy from their parent company, Facebook, continues ~ but only aimed at commonsense conservatives?

'When Obama was POTUS, he MOCKED children with Down Syndrome on late night tv, and nary a word of outrage from these same folks. But they’ll censor my post of my most favorite person in the world... Inexplicable,' Palin continued.

It is unclear exactly what incident Palin was referencing, although then-President Barack Obama was forced to apologize in 2009 after comparing his poor bowling skills to 'the Special Olympics' in an interview with Jay Leno on the Tonight Show.

Palin was slammed for her post featuring her son crying hysterically. People said she was being demeaning to people with disabilities

Palin continued: 'Unbelievable. And scary. Facebook continues to censor traffic flow to my website, too.

'Ummm, Zuckerberg, you were in Alaska recently.. did you not learn a thing about Mama Grizzlies when you visited?'

Controversy erupted after Palin posted the original meme, which appeared to be in response to intensifying protests over the confirmation of Supreme Court Justice Brett Kavanaugh.

The bottom half of the meme features her son Trig, who has Down syndrome, sporting his sweatshirt 'Homie with an extra chromie,' crying hysterically at Walmart.

In the caption next to her meme, Palin wrote: 'What protestors [sic] (who can't explain what they're protesting) think we see -vs- what we really see,' followed by a laughing emoji. She also issues a brief apology to her son: 'sorry Trig!'

Protesters is spelled wrong in both the meme's caption and the writing next to her Instagram post. Trig has been pictured in the sweatshirt before.

Palin's post came under intense criticism by commenters on Instagram.

Halfevild took a jab at Palin's intellect, writing: 'Thank you, Bore of Babble-On, for once again reminding people why you're accurately referred to as a World Class Idiot and America's Resident Dunce.'

Petparker76 was kind enough to bleep out their own curse word writing in a lengthy comment onto Palin's post: 'What kind of piece of s*** uses her son to try to insult people. Especially when you guys were holier-than-thou when a cartoon used his image. And by the way it's not an insult to all of us who actually know why people were protesting.'

'You don't because you don't know anything and you've proved that to the world. And to be compared to someone with Down Syndrome is a compliment. They are beings that shine brightly, and love fiercely and the ones that I know that have the syndrome are some of the most intelligent people that I know. The fact that you don't know that and you have a son with Down Syndrome shows you do not deserve him. You should be ashamed of yourself.'

lovehealnourish wrote: 'Wait are you saying protestors look just like your beautiful son?? I couldn't imagine how you and the Right would act if a Democrat posted this.'

Another commented: 'This is a disgrace and demeans all developmentally disabled.'

Palin gave birth to Trig in August of 2008 and has previously defended against attacks on her son's disability

Palin has, to her credit, fought against attacks on people with Down syndrome in the past.

Palin criticized a 2010 episode of the Family Guy that showed a character with Down syndrome whose line was: 'My dad's an accountant, and my mom is the former governor of Alaska.'

Palin called the cartoon a 'kick in the gut.'

She has also voted in support of banning abortions for women pregnant with Down babies.

However in a 20/20 interview she admitted when she found out Trig would be born with the genetic disorder, she understood why other women may choose abortion.

'I knew that the option was there... I thought again, for that split second, ''OK, now I know, too, why, when that fear strikes you, because of the unknown,'' she said.

'I understood then, too, why a woman would consider [abortion] an easier path to perhaps, if you will, do away with the problem, instead of understanding that every child has purpose. There is destiny for every child. And it can be good, in our world. And that's what I held onto.'
