I disagree on this one vehemently. This is spoken like someone from a privileged position of the majority or in a relatively cosmopolitan area.
Be an atheist or agnostic in the Bible belt. You will find yourself either in conflict or holding your tongue A LOT.
Be a nurse in the Bible belt. You will get attacked by your family for promoting "vax conspiracies".
Normally, I would just hold my tongue in these situations, but I've stopped doing that. I'm quite a bit more outspoken lately and becoming moreso. Why?
Because I have had people breathe sighs of relief when I tell them up front that I am pro-vax and pro-science and pro-medicine and if they don't like it they can shut up. Because I've had multiple people crying with gratefulness because I stood up and forced some asshole yelling at them to back down. Whole swathes of US society are taking advantage of the fact that decent people normally avoid conflict.
That is unacceptable. And it stops with me. I refuse to allow this to continue quietly.
I won't seek conflict, but if you want to avoid conflict it's time for YOU to hold your own damn tongue, thanks.
