This isn't your college or work place break room. If people are saying something you disagree with you can just say it and you won't be fired or ostracized for it. Yeah, people will probably get angry and say mean things to you but those are just words which can be ignored. Offence is taken, not given.
This is mostly for the lurkers who upvote unpopular opinions but don't comment. You can speak up - you're not alone.
That's old style thinking. If that type of matching isn't already automated and running, it will be soon. They'll click a button and find you everywhere if you've left enough breadcrumbs, so there won't be any lengths to go to. And as someone who has gone through the cybersec exercises of hardening browsers against fingerprinting, knows what VPN can do and more importantly what it CAN'T do, etc, I can say there are precious few people in the world going to the lengths required to stay truly anonymous. It basically has to become your top priority and constant focus if you want to be successful.
