You should be nicer, and considerate of others feelings. The world if full of wonderful people, and to make the world even better, we need to treat others better. We need to put our differences aside, and look towards a happier future. Just like it says in the bible, we need to love our neighbors as ourselfs. Saying on nice thing to somebody may just happen to impove there life significantly. If everyone was nice to eachother, the world would be a much more wonderful place.
No worries supertman, guys like this don't bother me, I just report them and move on.
