Mitt Romney is just one of a number of politicians and high-profile personalities to offer condolences on the death of Sally Ride, the first American woman in space, on Twitter and other social media outlets. But the Republican presidential nominee's response isn't sitting so well with some, particularly given the posthumous revelation that Ride was in a long-term relationship with another woman.

In his original Tweet, Romney wrote:

Sally Ride ranks among the greatest of pioneers. I count myself among the millions of Americans she inspired with her travels to space. — Mitt Romney (@MittRomney) July 23, 2012

Not surprisingly, Romney's tweet quickly drew a number of heated responses on Twitter, with most pointing to the former Massachusetts governor's track record of not supporting lesbian, gay, bisexual and transgender (LGBT) rights, including marriage equality. Some replies were also directed at Sarah Palin, who also tweeted her condolences on Ride's passing.

The indie-rock group Mountain Goats were among the first to respond, noting: "Kind of despicable & grotesque that her partner of 27 years will be denied federal benefits, don't you think?"

Others were similarly impassioned. "You don't get to speak about us with sentimental gushing after we're dead," wrote another user.

It is believed that Ride never publicly addressed her sexuality during her lifetime. Describing her sister as a very private person, Bear Ride told Buzzfeed: "The pancreatic cancer community is going to be absolutely thrilled that there's now this advocate that they didn't know about. And I hope the GLBT community feels the same. I hope it makes it easier for kids growing up gay that they know that another one of their heroes was like them."
