I saw that particular hashtag on an S-Moo-V last weekend and I looked it up later to see what it meant. Apparently, Mind Your Own Tits is a social media movement to normalize breastfeeding, I'm guessing in such a way as to make people stop staring at beefers or telling them to cover their udders in public.
First of all, breastfeeding is not abnormal, so there is no need to "normalize" it. If you have a loaf, you'll probably start producing milk which you can choose to feed to said loaf. What's to normalize? Tit-feeding would be fine if the same respect was given to women who want to pull out their boobs without latching a crotch maggot onto them. Why are boobs allowed to only be exposed for breastfeeding? Either all boobs can come out or no boobs can come out, none of this halfway/exception shit. By this logic, people should also be able to have sex freely in public if it's for procreational purposes because apparently if behavior typically viewed as sexual is for babby, it's acceptable to do in front of an audience.
Like Moos need more social support for being exhibitionists. If I start masturbating in front of a beefer, can I tell her to mind her own cunt if she takes issue with me getting off?
