Trans men absolutely do experience misogyny, and often do not benefit from male privilege much or at all unless they medically transition to some degree with the goal of consistantly presenting as a cis male. Much of the oppression we face in the world centers around a hatred of women, and is experienced within the context of being considered women by those around us.
The tumblr trans and feminist communities like to ignore this reality in order to justify hatred or bitterness towards trans men, and it’s something that should be taken very seriously because trans men are an oppressed minority. Attacking trans men is not the same as attacking cis men, and that context needs to be taken into account when discussing gender politics and feminist issues.
People who have been socialized as women by the people around them, and who are so often still viewed as women by the communities they live in, cannot safely and respectfully be regarded as holding the same privileges or experiences as cis men do. Not all men are given the same opportunities or advantages, and trans men do not come from the same history of systematic or institutionalized privilege.
We are men, but we must take very different paths from cis men and work much harder just to be able to assert that as a fact, much less benefit from it. Even more so for those of us that are queer, or who do not adhere to typical male stereotypes and societal expectations.
On a side note, pitting trans people of different genders against each other is divisive and is a common tactic employed by those in positions of power seeking to weaken the social movements of minority groups. It’s important to acknowledge our differences and examine how that effects the ways we experience privilege and oppression, but when we use them to justify conflict and instability in our own community, we are harming our own efforts. When a minority group fights within itself, it’s important to ask ourselves who really stands to benefit from that.
