I've seen people say there's good weird and bad weird, and if you don't mind calling yourself weird it's probably the good kind.
As for calling maga people weird I think it's effective because their whole deal is about vibes. "We're strong, we're smart" and it really bothers them to be perceived otherwise. It's also not something you can "debate". Either people accept it or they don't. What are you going to say "no, I'm not weird"? Sure thing buddy.
I like and use signal, but of course the problem is convincing someone else to start using it in order to send you a message.
