Hi ZiaAngel, first of all welcome.
Second, I've realized it is in our best interest to try and not read hateful comments posted online...I had a similar experience recently, here in my country a transwoman participated in a reality show and became famous, and she was featured in a video interview posted on Instagram and there were so many hateful comments, people saying "no matter what you do, you will always be a man" and things of that nature. It hurt me, it made me think about how I am going to deal with such hatred when it happens to me. It's sad really, but all we can do is get a thicker skin and hold our heads high.
About your parents, I can't really help you much with that, I will just tell you that you should come out whenever you feel you need to, and whenever you feel is safer. Don't need to rush it if it's gonna hurt you.
