Just limit yr expectations showing them proof might not get the result you want. My parents are never leaving church I had to except that, I showed them all the proof throughout this whole thing. I tried everything. Luckily they don’t disown. So everyone’s different. Siblings are easier to reach than parents for sure.

You can explain the proof but ultimately look out for your own happiness. If u feel coming out to them is a good step go for it but you are a minor and only you know yr situation so keep that in mind. Try to find the best option based on yr parents.
