I remember that episode of DWTS. Maks basically said he didn't care what she had to say when he and Meryl went up to speak to ErinI wonder what the training was like for the pros growing up. Obviously they're made of tough stuff physically and mentally, but equally I remember numerous pros from DWTS being very quick to condemn Abby Lee Miller (Dance Moms) and her tough teaching methods. So clearly they weren't taught like that and had a more balanced approach. Mark & Derek were among them, so Shirley didn't ever reach that level.
I thought Julianne came out and said stuff against Shirley and Corky though? I could be wrong.
