Just need some opinions on something

I am not sure if I am being too naive currently but I have been wondering if it was wise to try coming out to my family in the forseeable future.

My mom has made some not so positives comments on the LGBTQ community and is a catholic. I am really unsure on being able to come out to her and that is especially a big problem since I live alone with her (since my parents divorced years ago). She does treat me pretty well right now though, but I am unsure on how much that point could really hold up if I were to come out.

Then I also have my dad's side which gives me especially conflicting information. I can tell we that he does care about me and has told me that he will always be there for me, but my step mom and step sister had also made some not the best comments on LGBTQ. For example, when my dad/step mom (forgot who it was exactly but both were involved in the conversation) asked if I have a lot of "other kids" and when I asked to elaborate they basically just listed people from the LGBTQ. I am unsure of I am overreacting on that but it feels like an odd way to word it. And additionally my step sister just told me a transphobic joke in the past.

On a side note, I have heard racist remarks from both my mom's and father's sides they both appear to be pretty conservative minded

I am probably just being naive but do you all think there is a proper chance for me to be able to come out? And I apologise if I don't respond much in the replies, I kinda get anxious when it comes to that >~<
