On equal respect to cultures and ways of life

On liberals (allegedly) having to give equal respect to cultures because liberals are committed to equal respect for persons:

"The obvious problem with this argument is that illiberal cultures typically—I am tempted to say necessarily—are committed to violating the cannons of equal respect. Equal respect for people cannot therefore entail respect for their cultures when these cultures systematically give priority to, say, the interests of men over the interests of women."
