Hi,
I appreciate your question and your courage in asking. However, I would challenge your premise that political advocacy requires telling people who to be intimate with.
I don’t men to sleep with me if they’re not attracted to me. Rather, I want the men who already are attracted to me to stop treating me like shit because they hate themselves for being attracted to fat or disabled women. Similarly, I want fat women to date whoever we want, regardless what that person looks like. We’re not being more political by dating fat men.
