Welcome!
Unfortunately, Indian Summer nails it: people living in fairly-large United States cities often have an easy time of it being vegetarian or vegan. In other parts of the world the pickings can be slim. (But a vegan friend of mine went to a vegetarian convention in Thailand, and said she had a great time... so I guess you get a lucky break sometimes.)
And yes- it's lousy that animals are seen mostly as "things to be used" almost everywhere.
I am interested to hear about Thailand. Now I live in Australia I had thought of returning to SE Asia though was not sure what I would eat!
I keep my options open these days and I try to be creative now I live out of the city. Just today I went and asked the one decent restaurant in town if they can do a vegan meal for us tomorrow night for my partners birthday and they were happy to oblige ( though I did laugh when we went through the list of what we do not eat-eggs,dairy, cheese, meat and she says but fish is alright?
