Btw why do some Western men on this site sometimes mock me or even make fun of me but male expats in my city don't in person?

I have noticed one thing that some men on this site from Western countries mocks me or makes fun of my for years and even now at 24 and they are often older too like 40+ maybe because of my posts which can be immature at times. Some have been mean in the PM too when I just try to do a harmless prank like saying "Hey man I heard you said some mean things about me before. Why?". But the expat men in my city Bangalore, India don't try to put me down or mock me. Like I said there are many expats in my city from multiple foreign countries and I see them a lot in UB City mall, Lavelle Road and Church Street. You all know from my posts that I talked with multiple foreign expat women. But I also do say Yo man and making hand gestures to Western male expats who are mostly white and sometimes black too but they just smile. I also say the men hello and wave at them but they just smile and say hello and many of the men are older too. So why don't these older Western male expats try to mock me or put me down like the men of this site?
