Parasite, the White Knight in me wants to applaud you for defending the honor of your lady, but Von is right, doling out beatings in public is a sure fire way to get a criminal record and never land a respectable job.

I've always been super tall (6'6" since I was 16) so I'm never harassed despite being weird and sort of creepy. If somebody's angry with me I just refuse to take them seriously, that always yields satisfactory results.
Bullying has its merits for building character and encouraging non-faggy behavior in adolescents, but grown men should strive to rise above such petty behavior.
edit: Mind that bullying is different from trolling, which is an essential life skill.
