Conservatism by definition is thinking "Things are good right now, let's not change anything" or even worse: "Things were better before, let's go back to that".
The issue is "better for who"? Women, queer people, POC, working class people were NOT ok. Implicitly you can see that conservatism is bigoted by (at a minimum) ignoring or misrepresenting the realities of people they don't care about. It's just that lately, more and more conservatives are explicit about it and showing their true colors, but the philosophical underpinnings are the same.
You are clearly not a victim of these issues and the situation is so alien to you that apparently the only way for you to relate to them is via the news. Violence and prejudice are things that happen to "other people".
Real people are suffering real oppression every day. Some in a small almost invisible way and others live in permanent fear of violence because of who they are.
That things were worse in the past is no reason to stop progress. And things did get better because people fought for them, often to death.
I hope you are arguing in good faith and have the moral strength to accept you may be blind to some realities and reconsider your beliefs.
