// And the 'excuse' for hostility from the LGBTQ+ community is so often that others - even though they're right - don't agree with them. //
The "even though they're right" is so revealing here. To pretend that any such discussion is moot is already problematic, because people who are convinced that they are right don't debate so much as preach. And even to the extent that someone is "correct", they can still be hostile, aggressive, unpleasant and discriminating in delivering that message -- and shouldn't be. And finally, sometimes it's just good practice to "pick your battles". You may be "in the right" on a given point, but in this setting, at this time, when talking to this person, it's not relevant and it's prudent to just move on.
