In all seriousness, I don't necessarily condemn the criticism, it's just that it tends to be misguided and generally ignores the fellowship that is part of celebrating quasi holidays like this. It's one thing to use cultural markers as a way build commonality, it's another to use cultural markers to justify destructive behavior (in particular, uncontrolled inebriation). To the latter, Saint Patrick's Day and Cinco De Mayo share the same problematic justifications that warrant criticism in the proper context.
