I’m sorry you get treated poorly as a woman online. Some subreddits/online communities are more toxic than others. I think it’s best to meet men in real life than dealing with them anonymously online though I understand that can be tricky in a pandemic. Depending on where you live, you can join Meetup.com for meeting people based on pandemic friendly hobbies such as hiking with dogs, rock climbing, etc which you will meet people of all ages.

I respectfully disagree that men can only be friends with women they find unattractive. You can acknowledge that someone is good looking without wanting to be in a relation with them. There are factors that need to make it work such as both have to make it clear that there are no ulterior motives.
