Mouthy Infidel is making the desire vs. behavior or thought vs. action argument.

I remember making this argument back in the 2000's debating (against) homosexuality and gay marriage in /r/atheism, /r/politics and /r/Christianity. I tried to explain to people that hating the sin is different from hating the sinner and that being born homosexual and acting on those desires are two different things. We can't choose how we are born but we can choose what we do, or at very least, we can choose whether to accept our [broken] nature or fight against it.

That said, in this hypothetical scenario where someone is a pedophile who hates that part of themselves and wants to fight against it, they wouldn't be out there trying to foster mainstream acceptance. They wouldn't be advertising it like it's something to be proud of. They would avoid schools and anywhere with children like the plague on their own rather than being forced to do so. They would be seeking any way possible to "fix" themselves, and bar that possibility, they would accept a lifestyle of self-denial because they know it's the right thing to do.

However, the behavior of someone living this way and the behavior of these people on the left betrays their true intentions. They don't want to fight their nature, they want to be accepted and then later celebrated, following the precedent set by the LGBT+ movement before them.
