I guess the point is that your sexual orientation is not a choice, whereas being a homophobe is a choice. And not a choice that should be pandered to in public. What homophobes do and say in private is their business. But there should be no place for discrimination in public, no matter how “sincerely held” their homophobia.
Oversimplification, it's not just virtuous to hate injustice and hate superstitious religions. You need to proceed in a way that will protect rights for all, there are prices that come with maximum freedom and liberty, but those freedoms mean a lot to all people even good non-bigoted people. So everyone should stop pretending just because you can throw your hand up and say "I hate religion", and "I hate homophobes" you are somehow making some kind of intellectual case and not just virtue signaling which is pointless and self-serving. Many provocative discussions have a broad spectrum of viewpoints that exist, if its this cake case, or climate change, or immigration, of abortion, there are not just two black and white far left and right ideas, but many people trying to walk the center line of sensibility in the middle. Too often the discussion degrade into you are all this or that, usually by the people with nothing intelligent to say and nothing to add to the debate.
So stop trying to paint everyone into an extreme for wanting to have an idea that evaluates a broader range of issues at play and doesn't reduce it to nonsensical virtue grabbing. Its very nice you dislike homophobia, congratulations, me too! and probably most people, I wish it would go away. Now can we have a discussion about the details of how this impacts free speech, free exercise, and not pretend like its a debate on whether or not being a homophobic ass hole is good or not, because most all of us already believe that's NOT GOOD.
