Pretending not to like something to seem cool costs you the friends who like it too.

Hiding an interest does more than make you slightly less honest; it makes you invisible to the people who were looking for exactly that. Those friendships get made when somebody says the uncool thing out loud first, and if you never do, the person who would have lit up walks straight past. The protection costs you the recognition.

Mention the real thing once this week, in a group where you would normally keep quiet. Wear the shirt, bring it up, put it in your bio. Watch who comes over, because that is the whole mechanism, and it cannot work while you are hiding.
