Yes, some people are insulting to casuals... but they aren't completely unjustified in their anger.

The point is, Hardcores are generally willing to meet halfway on something. Casuals are generally not.

For example... the death penalty. Most hardcores would like to see a significant penalty for death to make it mean something. However, most are also willing to accept a more lenient death penalty to meet the Casuals halfway.

But the Casuals will "have no such thing!". They aren't willing to even consider having a death penalty "because it's not fun". They aren't willing to compromise, which pisses people off. If you aren't willing to discuss and compromise, you have no right to sit at the table.
