Why do hardcore gamers hate casuals so much?

Casuals subsidise hardcore gamers. Current development budgets would not be sustainable without them.

Hardcore gamers hate that, and the concessions made to them.

Hardcore games existed before casuals entered the market. Hardcore games WERE the market, originally.

I'm pretty sure the main complaint is historically hardcore series getting fundamental changes to appeal to a wider audience, one that seems to either complain anyway or not buy the game regardless.
