People can chose whatever the fuck they want for whatever reason they want.
I never said otherwise. People can choose whatever they want, but they deserve to be educated about what they are choosing. Separate threads would prevent that. Once they do know about the strengths and weaknesses of the different setups, in relation to their personal situation, they can make their own decision and I will never criticise them for it.
As for my opinions aren't facts, are you saying that input lag, square pixels, uneven line upscaling, downtime upon resolution change, hiccup scrolling with certain consoles, are just opinions?
[edit] Mega, there are perfectly legitimate reasons to prefer an upscaler. I could think of space, not wanting a separate display, wanting to play on the main giant display of the living room, etc. I don't diss on upscaler users, but the discussion we're having is needed so that people know about their options. In separate threads, people talking about upscalers wouldn't even start to consider using a CRT, even though they could go for this solution if they knew about it.
