We all connect with these members differently. Some people love Lindsey's craziness, some love Stevie's whispy, mysterious persona, others like Christine's classiness, etc. It's different for all of us.
Personally, overall, I like male singers better than female, but I do like a few female singers.
There are most definitely lots of people who don't like Lindsey's pawing action and his over-the-top antics he's doin' this go-round, but hey, ya can't please everyone all the time.
One more thing, in response to Lindsey going crazy and Stevie not having to go insane, back in the day, when Miss Stevie was in her altered state, she would be very wild onstage, sans any instrument excecpt a tambo, she would be indecipherable at times and kinda scary too. Of course, like I said, she was altered, but still, nonetheless, she was very crazy...i.e. Red Rocks. She was insane like he is today, only in a different way.
Today, she's off drugs and YAY to that, although, we get a more subdued Stevie, but would you rather have an unhealthy Stevie giving a wild, crazy show or a healthy, more subdued Stevie giving a good show? I pick the latter. I wish she still had that crazy fire in her, but I understand why she's not that way anymore.
