Don't forget that these actresses live, and mix, in a bohemian world, in which holding to certain seemingly radical notions about individuality is the norm.
A remarkable example of that is the die-hard support of a sexually abusive cult leader Gerry Healy by Vanessa Redgrave:
After Michael Banda, the general secretary of the party, publicly commented that Healy had probably sexually abused more than 26 women,[18] Vanessa Redgrave said at a press conference that "these allegations are all lies and the women who are supposed to have made them are all liars. I don't care whether it's 26, 36 or 236. They are all liars"
