I don't think it's just a Twitter thing. I don't do Twitter, it doesn't float my boat, but YouTube has some pretty terrible comments in Sims related videos. Towards the game and towards simmers. People fail to realize that this game wasn't made for one type of player, but for a variety of players. Those who like realism or supernatural or fantasy or whatever. Not everything is going to make everyone happy all of the time and it makes them mad so they have to go and cry to everyone else and complain about how they hate what EA is doing all while buying every Sims pack that they claim to hate.
I for one let my Sims Flag Fly and if anyone tries to make me feel bad for loving the sims, well I feel bad for them more for not having something to love.
