Based on my post, yes, that would fit. Allegations of child molestation are serious enough to incite violence against groups of people who are undeserving, and as someone raised Baptist, this would be something I would hear a lot from people who wanted to exclude or discriminate against Catholics.
Ultimately though, "hate speech" is a hard thing to prove beyond a reasonable doubt that the speaker/poster was posting with the intention of hate, which is why it's seldomly used in prosecution. The above post could also be seen as a jab at recent news regarding a priest who got caught molesting children, or a criticism of the church rather than the adherents.
My issue with the banning of queer topics and members is that not all Christians are LGBT shunning. There are plenty of Christians who are queer, or have queer family, or are affirming or supportive of queer people. To ban the discussion or participation of queer topics and people would be to deny a group of people membership based on their interpretation/ belief/ or denomination of Christianity. To make that a rule in a general Christian sub comes with the implication "if you are queer affirming, you are not a true Christian and aren't welcome here"
The issue above feels more of a matter of exclusion rather than hate speech.
