@daniel345 coz girls who are dumb ,
1. can't defend themselves
2. easy to take advantage of / gets manipulated easily
3. soothe the fragile male ego
4. men get to MANSPLAIN these girls
5. their feelings are often disregarded as they're dumb
eg. - the beautiful dumb blonde that every man loves, but the smart glasses wearing brunette which is a bitch in eyes of guys
