Tidying up Twitter

I belong to Twitter, in that I read the tweets of people whose opinions interest me. I follow 63 people and I have about the same amount of followers  –  some are people I know and some aren’t.
I have never been trolled, possibly because I rarely post a comment, even when I am in fervent agreement or fervent disagreement with a tweet.
But I have seen many awful (often quite foul) comments that sometimes accompany tweets as ‘replies’.
 
And here’s the topic I find interesting. The worse the response, the more likely it’s written by a man.
I read positive comments from both male and female members of the Twitterverse, but negative and insulting comments are mainly from men. Hateful comments are almost always from men.
Why is this so?
 
Now, please don’t start thinking that I am one of those females who claim that ‘all men are horrible’ or ‘all men hate women’ and so on, ad nauseam. I’m just stating that it’s usually men whose comments on Twitter and Face Book are the nasty ones.
I won’t quote any – that would be furthering their agenda. Anyone who follows Face Book or Twitter can see them easily enough. (And they’re usually anonymous).
  
I will never imply that ‘all men’ are anything. This month’s news story claiming that a woman said that ‘all men are rapists’ was blown out of all proportion and it also was not what was said.
But, but…there are SOME men who are horrible, there are SOME men who (seem to) hate women and there are SOME men who are rapists.
But it is not ALL men.
 
In my family- close and extended, in my circle of friends and amongst my work place acquaintances I have never come across any really horrible men or men who hate women or men who are rapists. In that I am fortunate. Nor do I know any men who post crude or hateful remarks as Twitter or Face Book comments.
But SOME men do.
Again, I’m tempted to give an example, but NO. Most don’t bear repeating.
 
There are people (mainly men) who post negative comments about politicians, which I suppose is understandable and even acceptable, but there are some men who post nasty comments about women, just because they don’t like how they look, what they wear, what colour their skin is  - more than what they say.
 
Are there reasons why some men seem to dislike women? And why is it often subjects concerning empathy and compassion to which men react negatively? Has anyone researched this interesting topic?

​BUT... 
I am so pleased to read that Twitter is deleting (some of) some people’s followers. I haven’t studied  much about this new development but what a good thing to have the worst of trolls, robot nasties and anonymous abusers eliminated.
