um......no.
Please have some facts before speaking.
Facts? You want more facts, well:
Fact is, ABC is mainly left wing. You have other ideas?
Fact is, I've seen 3 shows....all PC-based.
Fact is, you may have seen 1 Extreme Makeover that was not PC. Thats not enough of a sample to conclude anything.
I suggest you continue to watch before deriding anyone else's observations.
p.s My prediction: The more popular Extreme Makeover gets, the more PC it will become. Give it some time before you jump to the conclusion that ABC has seen the light.
