I think it's less about gender and more about some people not being as mentally and emotionally invested as other random, total and complete strangers may be into sitting in front of a screen and bickering and/or desperately trying to show off what they know. Some people here are literately either so stubborn, prideful, egotistical, or their schedules are so empty that they desire to sit on their butt in front of a screen being argumentative and bickering endlessly for HOURS which is their business. But you cannot expect a random stranger who doesn't owe you anything and is not obligated to participate with a silly, unproductive, pointless hobby to play along.
It's funny, people say they don't care if they've been blocked... but the they go on to insult the people who blocked them. If those people legitimately didn't care it'd be more of a "eh yeah sure I've been blocked, we disagreed. Not really a loss."
Adding personal insults to the people that have blocked them is a clear indication they care. They might not care a lot, but they care enough to not brush it off.
I don't know how many girls have blocked me. I usually don't get into arguments with anyone, guys or girls, but I have noticed that I have been blocked by some people. Can't understand why. I think it's because I'm an Indian, and most people around the world are rather averse to Indian men.
I can't say for sure but I can only think of one occasion I thought I was blocked - I was surprised but on reflection I felt there was no point in worrying about it - I try to be in the moment as much as possible on the site so getting worked up about things would take away from any enjoyment I am having.
I've been blocked by many girls for that reason. Just yesterday a girl picked a fight in MY opinion and then ended up blocking me when I told her I didn't give a shit about her negative behavior towards me xD Most of those who have blocked me are girls that have lost arguments, and there are girls I didn't even know they existed that have me blocked.
I'm glad they block me though, the less immature people I have to deal with, the better.
