Because - like good little liberals they are - they believe that being beautiful, like being rich, is unfair, materialistic, and it leads to discrimination and objectification of women. Why do you think that People magazine's list of Most Beautiful People get more and more laughable every year? EVERYbody must be beautiful. So they go pretend to see beauty everywhere. Even where it does not exist. Otherwise it's discriminating and, of course, racist.

IOW, it's the old 'envy' thing again. Ugly women are jealous of pretty ones, so they demonize beauty just because they don't have it. Exactly the same as with wealth. Typical and characteristic of liberals.

Also, feminazis believe that pretty women, and/or those who wear makeup and perfume, are shallow, vain and dumb (yes, I know; can't you just feel the sisterly love?), who want to improve their appearance just to please men.

That's why 99% of ugly women are liberals. Because they can get away with showering only occasionally, and generally looking like something out of the garbage bin. For feminazis that is equivalent to "taking women seriously."
