Would you post what you want regardless of backlash?

Not sure if this is considered controversial and this is a personal story but I’m curious on how you would go about this.

So a lot of my family is deeply religious. Regularly church going, bring God into every conversation type of religious. Which is fine, I respect other people’s beliefs, even though I consider myself agnostic.

I have a lot of my family on Facebook and they are always posting about God. Saying how God can help stop the coronavirus and if you put faith in him you won’t get the virus.

Well in a way I don’t feel in control of my own Facebook. I don’t feel like I can ever post anything about being agnostic in fear of family backlash. Or not believing specifically in God. In my family the elders are extremely important and that would be considered disrespectful and I would be talked about horribly. One of my aunts who is Pagan and considers herself a witch also hides her beliefs for the same reason and has told me this.

Would you just block these family members? Or post what you want and not care. I’m an adult so I’m not sure why I still even feel this way!
