Treatment of Blanche

Anyone feel like the girls were a little judgmental towards Blanche at times? Especially during the Gil campaign. They’re supposed to be best friends sisters almost and they believed Gil, a politician at that, over Blanche. That’s always bothered me. Also in the episode with the pictures of Charlie in bed with Blanche; I’m not sure why Rose was so upset with Blanche and not Charlie. I get that the time was different but it doesn’t very sisterly.
