Hello and welcome to the forums. One thing you’ve already found out is there are all types of people here. Some are nice and some are not.
I would recommend that you ignore the ones who are not nice. But if you feel someone is being racist you can report their post using the “Report” macro at the bottom of each post.
The forums are for all sorts of discussions so if you want to look for someone to connect with here you can. But if you want to increase your chances of finding someone I would agree with those above that you should use one of the chat rooms where there are usually many more people and you can talk to them in real-time. Happy chatting
