I think it is possible/fairly safe to cheer for the Denver Bronco's or the New York Yankees, or Crystal Palace football club or Team SoloMid or whatever without making that one's identity.
Edit: Just now, someone showed me a video which claimed drinking apple cider vinegar helped prevent cancer. I tried to say that this is billshit because nobody can really say drinking something prevents cancer without a long-term study that I doubt this YouTube celebrity had done.
I don't claim I don't have a bias. But I don't think we should be sin free to cast the first stone on ideas.
