How does one come out? Living in a religious conservative family?

Well my parents know I'm gay but none of the rest of my family knows. My closest friends know and they're freaking amazing. But my parents and everyone else in my family are really religious and I'm tired of "being in the closet" like I don't think that it will get better until I can be myself everywhere I go. Now I'm not like fem or anything (nothing is wrong with being fem) but I just want to be able to walk around with my boyfriend and hold his hand. And if someone says anything about it then I can kick their ass. Plain and simple😀 anyone with advice please comment. I need to be me if that makes sense
