Can I post anything I want on my Facebook as long as Facebook have no problem with it

So I got religiously married (not legally married) nearly two months ago and someone from my in laws sent a picture of my Facebook account to my uncle showing the profile picture I was using .. and then my uncles messaged me asking me to remove my profile picture .. when I asked him who sent it to them they said “don’t ask stupid questions” so I told them that many people use that kind of pictures even my friends .. he called me brainless and said he never want to see my face again .. I think it’s my Facebook I have full right to post and put as profile picture whatever the fuck I want .. if Facebook didn’t mind then who the fuck r they to be butthurt ... this is the picture I had as profile picture
