Maybe so, but violence is not an option. Just disengage and say nothing. Otherwise, you position yourself with the enemy. The majority of Thai people don't want a violent solution at this stage. The attempts of those few of all sides to whip up violent feeling (to satisfy their own selfish agendas) are losing support.

Re. the alleged ineffectuality of Thai HR groups: at this stage there is so little public support for them that their most urgent need is to educate and inform, so that they can gather committed support. If everyone believes, for example, that it's ok for death squads to murder 2 1/2 thousand citizens, whether they were or weren't connected with the drug trade, or to murder a whole lot of Islamic Southerners by piling them up in the back of trucks so that they suffocated, or that the police & military & many politicians can behave like mafia thugs, then the most urgent HR problem is not the deaths - it is the ignorance and blind prejudice of the populace, all of whom, in an allegedly 'democratic' society share the blame.

Myth's solution is pretty much in line with that of the 'dark' forces here: if someone is a 'problem,' strike them down. That doesn't solve anything; it further polarizes & divides the society, and in doing so it increases the problem. If you really want change, talk to people who are not fanatics. Try to get them to see that they can make a difference. It's really not that difficult. Almost everyone can recognize the fundamental truths that HR are based on. Leave the fanatics behind; they'll eventually be regarded as 'the lunatic fringe'.

BTW, I'm not suggesting that public stands shouldn't be made where possible, or that AI, for example, should be let off the hook.
