Radqueer is a whole rabbit
hole where paraphiliacs (pedophiles, zoophiles, necrophiles, etc) and transIDs attempt to garner sympathy and acceptance by using similar language to the LGBTQ community. They
try to appeal to people's feelings by acting
like an oppressed group in
society that needs more acceptance.
It should be HEAVILY noted that most of us in the LGBTQ community do not support these people.
A transID is something such as transage, transrace, or transabled. A white
girl living in
America who identifies as Japanese would be an example of a transID. In this case, transrace.
A paraphiliac is someone with unusual sexual interests. It can be anything from mildly weird to illegal. More prolific examples would be pedophiles, zoophiles, necrophiles, etc.
This all falls under the umbrella of the radqueer movement.
