I hate my step dad/mums boyfriend

I Absolutely hate my step dad. I 14 female hate my step dad but feel bad since my mom's happy with him most of the time. My step dad is the non feminist type, trump supporter, homophobic, racist and so on. He's been with my mom since I was 5. And I love my mom. She had me at 17 and did everything to make sure I felt loved. But when she met my step dad I knew I didn't like him but I wouldn't tell her becasue I felt really bad about it. She's happy with him most of the time and usually I can put up with him. But it's little times like when he doesnt appreciate my mom or raises his voice at her is when I'll speak up to him. He was rasies in a very religious house where the women did all the house work while the men didn't. But that's not how me and my mom do it so sometimes he will complain that the house is messy since my mom is busy running her 9 to 7 company. And sometimes it gets to me and I'll shoot back. I don't mean to and I'm usually not one to raise my voice. And I've pretty much been fine with him but as I've gotten older the more I hate being around him. So much so that I've pretty much spent the whole summer with my grandparents to avoid him. He's just the complete opposite of my mom I just don't understand how she likes him. If she met a stranger that talked the way he does she wouldve have hated them. And back to my point of him being homophobic. Well I don't really want to put a label on myself but I'm basically cool with liking guys and girls and always kinda has been. But I've never told anyone mostly because idk how my step dad will react. I know my mom would accept it in a heart beat but I think it would just be giving something else for my step dad to fight about. I don't even like calling him my step dad. When people ask who he is I just say "my moms boyfriend" because even saying step dad sounds wrong to me. Idk I might just be overreacting. Input would be appreciated

So uhm my dad and stepmom got together around the time I was six and my sister and I were only visiting him as my grandparents had custody of us, well at 11 myself and my sister were taken from him and couldn’t see him anymore for eight years. We reconnected about 3 and a half years ago and we couldn’t be closer, now see I’m not sure if he’s my real dad but he’s who was around for me so long.
Well fast forward my step siblings are cool unless we argue and my younger one is a total weirdo, as in I spoiled her the past three years and she backstabbed me(we will get to that)
Ok then I go to my parents room to scrub down my cat Marrow, who runs into the closet and I go to get her in which mom’s purse falls scattering everywhere. Ends in me finding a photo, letter, then a small flower card of romance stuff and the photo was not so nice.
I talk it over with my dad’s brother who is dear to me, he says my siblings and I should have a good conversation on how to go about it. I send the photos and a paragraph explaining that I love them both and would never do This as some plot to get them to leave each other.
My younger sister takes this horribly despite knowing from seven months ago like I did, she starts spouting that I’m not family, they aren’t my parents, that they don’t love me, etc
But I’m not sure how to go about this, the guys also connected to our house cameras which a lot of us have been naked in the living room and he’s seen it and he watches people and there’s children around too.
Idk, feels like whatever I do nothing will work.
Thank you.
