Negative generalizations do far more harm than good.
Andrew Tate has been quoted making the following statements:
"Tate has described himself as "absolutely a sexist" and "absolutely a misogynist".[32] He has stated that women "belong in the home", "can't drive",[33] and are "given to the man and belong to the man",[2] and claimed that men prefer dating 18- and 19-year-olds because they have had sex with fewer men.[34] Tate stated that he decided to move to Romania in part because he was less likely to be investigated for sexual assault allegations in Eastern Europe."

Presumably all of those platforms that have rejected him, don't wish to support someone who has the potential to negatively influence young men with such misogynistic and chauvinistic ideology. They are not bastions of free speech; they are social media websites looking to maintain or increase their membership which is very likely at least 50% female.
Misogyny is considered an anti-social trait. Misogynistic attitudes in men increase the risk for substance use and depression. It is linked to violence, delinquency, unsafe sexual behaviors, and intimate partner violence (toward women). While misogyny can be the result of cultural influences in general, it is also believed to be the result of emotional suppression (inability to express emotions) and in men who believe they deserve special privileges, when this belief is challenged, they frequently lack the emotion regulation skills to manage feelings of rejection within the context of intimate relationships or in their attempts to form intimate relationships with women. As a consequence, these emotions are often expressed as verbal abuse, emotional abuse or violence.
