Ex-UFC Star Nate Marquardt Posts Anti-Gay Tweet, Ripped By Fans

Former UFC star Nate Marquardt is in the crosshairs of the LGBTQ community ... after he tweeted an anti-gay response to a commercial that showed two men kissing.

The 43-year-old, who famously knocked out Tyron Woodley in a 2012 fight, fired off the offensive comments after he said he saw the ad while watching ESPN+.

In his tweet, he said the commercial was "disgusting" and that he had to tell his kids "look away so they don't see two men kissing."

The former fighter, a devout Christian, added a throwing up emoji.

Immediately, the ex-Strikeforce Welterweight Champion was panned by fans for the remarks ... but he doubled down on his stance in further tweets.

As of Monday afternoon, the posts were still up on his social media page.
