You're right about the general sentiment acknowledging the seriousness only when you look at the center and left of society. The majority in the US however supports or tolerates the actual political decisions made, contradicting that level of importance.

When you paint people as being "disallowed" from more radical actions, the same question of true importance arises? The current trajectory leads to Armageddon, plain and simple.

My point here thus is about the proper scale on which people place the topic.

It's not a "lifestyle choice" to doom humanity's children to ruin.

Placing responsibility with the irresponsible is a cop-out.
