I was going to say "that's unbelievable" but then I know it's not... The past 5 years, I have been battling these types of leftist scum from all over the world when they descend on or pass through Singapore. Thankfully, my wife got over being afraid that the arguments would turn into a fistfight, but I never back down. Of course, the American leftist scum are the worst, thinking that their coolness at hating Bush and America will win them instant friends when they are abroad - not when they engage me!
Not that I wish you any physical harm, but thank you for not backing down with these vermin. One FReeper's friend/relative recently said, the only time in his adult life he'd been in physical altercations/fights was when he was around "peace marches."
