To play devil's advocate (pun not intended), this community poses an interesting quandary.

When seen in context, their rules do clearly prohibit any hate speech against the LGBTQ+ community:

Rule #5: Remember that we are all fellow image-bearers. We may disagree with people, but we are never to tear down another person’s inherent dignity and value as someone made in the image of God (Imago Dei). This includes those in the LGBTQ+ community. They need Jesus, too, just like we do, and we can’t say we represent Him while we tear down the works of His hands.

Rule #6: Banned subjects include ... Anything calling for direct/indirect violence against any individual or group, including LGBTQ+ individuals or groups; ...

Rule #8: This community does not affirm practiced LGBTQ+ lifestyles, with the exception of the ace/aroace (asexual/aromatic-asexual) lifestyle in certain contexts. However, abuse towards members of the LGBTQ+ community will not be tolerated. Pro-LGBTQ+ content is not allowed; however, sincere questions and discourse about LGTBQ+issues are permitted.

I'd be interested to see the admin's ruling in this case.
