From the little I know about this, the Red Shirts are /ourguys/ and the yellow shirts are astroturfed/royalist rightwingers.
the spectre of Thaksin Shinawatra still looms large. When he was Prime Minister of Thailand, he was know for rural uplift, tangible improvements to the lives of rural Thailand like installing electricity etc. The coup against him has been a bitter pill for well over a decade now.
Does anyone know any left wing thai groups?
