Why?

Just use common sense. Hilarious you guys are scared of wearing tshirts.

I'm actually scared of being shot in Canada. Your post has me concerned. I often like to wear red deer shirts too.

I don't think anyone is "scared" to wear a red shirt. It's probably more likely they would prefer not to do anything that might be considered offensive.

Now, odds are that one isn't going to get into any confrontation, based solely on the color of one's clothing. But, if confronted by a drunken fool, It could become just one more point of contention.

Around the heavily touristed areas, Thais are used to seeing tourists wearing just about anything. I'm waiting for slap shoes, beep nose and a bright orange wig!

Red, whether a sign of protest, or simply a fashion statement, is a color that stands out. We stand out enough. No need to wave a proverbial "red flag".

Not based in "fear', that's my reason for not wearing red. I would also advise against hot pink, lime green, caution orange or any other "standout" colors.

So funny Curt1591, like your style.
