I'm not sure if I interpreted correctly (sorry, if I did) but I got the sense that Indians were not particularly liked by Thais especially against other races. I am a quarter Indian myself (grandparent) but from the UK and didn't realise until someone told me.
Is this true and if so what is the reason and why?
Before any stereotypes come out - I along with many other Indians that I know in the UK are the opposite - fairly wealthy, smell nice, intelligent, quite good looking
