You should step down as an admin
While you may see it as merely "protecting" good content from "POV warriors" your policy of blocking users with whom you are engaged in disputes is extremely disruptive to wikipedia. It call into question the neutrality of wikipedia processes, and completely undermines the collaborative nature of the project. In reality, you are pushing a POV, just like every other human being. Your consistent abuse of power, in spite of constant reminders to stop, and in violation of numerous policies, leads me to believe you are unfit to have admin tools.
