She is just excited about dating again. I know I was when I started online dating after being married for 20 years and then divorced. She may also like to gossip a bit.
Maybe because you are not single at the moment you just don't share in the excitement?
I guess it also depends if she was more treating the men like objects and pointing out all the negatives and making fun of them. That would not be cool.
I think your respond is good except maybe tone down the negativity at the end.

Someone who is already showing you these profiles already may not fully understand.
