I don't watch many videos in my niche either, but I do comment on video that inspire me. I don't like to talk politics either, but I will comment about my faith on my channel. Most of the time my comments are questions. For instance I just bought a modular synthesizer to start writing my own music for my fishing videos. I've watch ton of modular synth videos asking questions and such. So my comment are often a question relating to what I'm trying to learn.
It's interesting that you mention your faith, because that's another big part of my thought process. I know pretty much every content creator talks about their faith (power to them)
What I sometimes find challenging is my LACK of faith. I have no issues with people's personal faiths and such... but because I DON'T have any faith, and sometimes I can be a bit (internally) vocal about my displeasure of how some treat and use faith... I do often find myself biting my tongue because I don't want to offend others.
I don't mind talking about it here too much because it's not on my channel, but I find the idea of actively avoiding discussions about faith, and my discomfort around conversations about faith can ostracise my from people that I admire that I know have a strong religious belief. That's why I tend to stay quite.
That said, I'm also teetering on using my platform as a voice. Not in a preachy way (lol, that sounds ironic coming from me, but i think people will know what I mean) I don't want to tell people how to live their lives or what to think and feel, and i don't want to make people uncomfortable with my views... but I also have strong views when it comes to support for groups that historically have been really hurt by religion in the past. It's always a difficult one for me..
Also when I get "god bless" and "thoughts and prayers" comments on my channel, I do appreciate the kindness behind it, but it also makes me feel a bit awkward as well. Kind of like if one religious person KNOWS another differant religion doesn't practice the same traditions, and still goes out of their way to wish them a religiously specific thing, making things awkward.
Was especially uncomfortable after my mother passed and I got all the prayer wishes... I mean, I appreciate the love... but in my heart it really stung. Lol probably going into too much detail there, but that gives extra insight into what I mean about comments, and trying to be careful about what I do and don't say in order to "not offend" people, incase I look "bad" or I make my "brand" look "bad"
Alway an interesting topic of discussion regardless
