For that matter, I'd include myself in the latter group. I'm reasonably vocal here - usually in an attempt to simply share my perspective, as it's not of the prevailing position in this community.
Sure, "the gun nuts" have a different agenda than the larger community. We're gun nuts because that's important to us. I can't think of anything that I've ever said (or seen said) in that community that should be secret. Lots of things that could be easily taken out of context, sure, and a fair number of things that are just plain inappropriate - but you could say the same for any community.

Some of them, absolutely.

I've never heard of that channel - though, granted, I'm not really a YouTube kinda person. It looks like what I'd call "Boomer content". I don't mean that in a negative way exactly; that's the kind of thing I'd expect someone in the gun community in their mid-50s or older to watch. The younger generation (say, 20s-40s) is watching things like "The Fat Electrician".
