I have never understood the discomfort around trigger warnings. Society has used them forever in areas that are considered sensitive. When the news warns you they're going to show graphic footage or that a story involves sex - those are trigger warnings. It's simply displaying common minimum level of empathy for the experiences of others.
Safe spaces are more complicated and (inherently) restrictive and so I understand the discomfort around those too. You can allow controversial / awful groups to exist (Nazis, KKK, etc) and provide trigger warnings for their events. Indeed, I would think that having 'opposition' groups and hosts provide their own sets of trigger warnings would be a fantastic introduction to outsiders.
