Don't we have a waifu thread so we can steer clear of OP's faggotry?
TsundeRie's are notorious for behaving exactly like what you describe. I believe aside from Shana and Louise there are 2 more characters voiced by Kugimiya Rie having the exact personalities at the same time, and 2 dozens more to this day.
However I wouldn't call it an era of Tsunshit. At least we had Kyou from Clannad, one of the last classic tsunderes.
