Here's Moonchild in 2020 announcing that he will no longer accept donations through Patreon, because he claims they got "political" by putting a Black Lives Matter banner at the top of their home page. He instead endorses the "politically neutral" Paypal, owned by a billionare who has never done anything political.

Here's Moonchild in 2022 complaining about "SJW"

Here's Moonchild's number two person Athenian200 in 2024 complaining about how terrible the gays on "Mastodon" are:

Now let's talk about Matt Tobin. To be clear, Tobin is not involved with Pale Moon anymore. For several years he was the number two person. He was a very outspoken Trump supporter, and he'd frequently derail Github discussions with rants about how SJW Marxist Killary is coming to force you to be gay. He would quickly ban from the forum anyone who criticized this behavior (even people who agreed with his politics but didn't want him to rant about it in unrelated git issues). Moonchild never criticized or reprimanded Tobin for this behavior and kept him on for a long time.

In 2022, Moonchild and Tobin got into an argument about the correct format for extensions, and Tobin ended the argument by insulting Moonchild and trying to deliberately break the PM website. Moonchild was able to restore the site and boot Tobin from the project. But it's worth noting that even after parting ways, Moonchild never denounced Tobin's bigotry.
