Most of the arguments presented for and against Brexit were pitifully under-informed, bereft of any long term planning, and simply appealing to people on an emotional level. Politicians on both sides of the argument seemed more interested in rabble rousing and fearmongering rather than trying to make a reasoned assessment of what both scenarios might look like once the voting was done, and the back-slapping and champagne quaffing was over.
If the 'experts' whose job it was to make decisions on these things, and present them to the public in an understandable but comprehensive format, were unable to formulate a clear picture of what the choices entailed, then you can forgive your average person on the street for feeling they don't have sufficient tools to make an informed choice.
"You want to vote for the Heliotrope party or the Mauve party?"
"What are their policies, and what will the country look like under them?"
"Don't get bogged down in the details. Just listen to your heart. Mauve is an awesome colour, and anyway - look at those stupid Heliotrope voters. Only an idiot would vote for the Heliotrope party. Just look at them"
"Alright. I'll vote Mauve."
Besides, even a tossed coin might land on its edge every once in a million throws (most likely less than that, according to my Google research). Sometimes it's valid not to pick a side and, glib coin throwing references aside, all of our circumstances are different, as the OP eloquently describes.
I think that, at this stage, the overwhelming majority of the fanbase wants the same thing. Chansiri gone. Just as in the case of historic revolutions, we'll never see every single person with a shared goal agreeing on the correct method to accomplish it, but usually if enough people want the thing, and are prepared to take action to achieve the thing, they stand a very good chance of making the thing happen.
Getting distracted by falling out with fellow fans who want the same thing, but aren't prepared to take the same actions as we are isn't going to get rid of Chansiri any sooner.
Increase the peace...
