Are Flutherites becoming more aggressive?

Has anyone else noticed an increase in general hostility lately? I’m under the perception that on some controversial issues tempers seem to flare more than usual. It appears lately that Republicans bashing Obama before the elections have been given more opportunity to debate their standpoints than some valid opinions coming up lately.

I’m under the impression the community was much more benign a short while ago. Is it just me or has anyone else noticed it?
