Some took to the streets to support the Women's March on Washington. Others took to Twitter to question it.

More than 1.5 million people worldwide joined in the Women's March on Washington and its sister demonstrations, including men. Yet some shared their disdain on social media for the march's female label. Others called the march a thinly veiled anti-Trump protest.

Piers Morgan, a British journalist, has been trending on Twitter throughout the day over his slew of march-related comments.

He wasn't the only one. Michael Flynn Jr., a former member of Donald Trump's presidential transition team who was fired after circulating the fake "pizza-gate" story about Comet Ping Pong Pizza in Washington, D.C., ridiculed the women's march on Twitter:

Women and men alike called them out for mansplaining, arguing that by ridiculing or questioning the march the critics were ignoring or dismissing the concerns of women and other marginalized groups associated with the demonstration.

But the ridicule doesn't only come from men.
