As I've said, there are a lot of topics that do not demand 5.5 as the example game (general gaming topics, things that apply to lots of D&D-style games, etc). Many of those discussions take place in the D&D forum.
Look, I am very sorry, but we live in an imperfect world. There will be cool things in the world that are in places that are not good for some particular people.
I, myself, have an issue with roller coasters. That's my own issue. Now, there are things at amusement parks that aren't roller coasters. And fun times with friends to be had at amusement parks that aren't riding on roller coasters.
So, I have a choice - I can go with my friends to the amusement park, and I can enjoy what I can, and respectfully not take part in things that aren't my bag, or I can go to the amusement park, and be a complete pill about how horrible roller coasters are at every opportunity.
If I do the latter, I am the problem, not the roller coaster. If, when I go to the amusement park, I find I cannot resist the urge to be a nuisance about the roller coasters, then I really ought to avoid the amusement park. Yes, my friends will have fun without me. Such is life. Making my personal issue into a problem for them is not justified by FOMO.
Same principle applies - if someone has a personal issue, they have choices about when they raise those issues. If they cannot show some wisdom and restraint, they make their issues a problem for those around them, which is decidedly uncool.
So - wisdom and restraint. Folks have to learn to pick their moments.
