Then stop using language that divides, use language that brings people together.

Claiming one group has blood on their hands only turns people who identify with that group away from hearing anything else you may have to say. Which is the exact opposite of what the world needs. We need more open dialogue, not more division.

By attacking specific groups or ideologies you are triggering millennia old survival mechanisms within human brains that makes them see you and your beliefs as a threat to their survival, as disagreement with the group a human currently resides historically leads to higher likelihood of exile or death as the group rejects them for their new beliefs, this drives them to further align with their current social groups views and shuts off the pathway between your mind and theirs.

You may have other posts in the future that may make someone drop their adherence to dogmas within their group and drive them towards more independent sovereign thinking, but they're only going to hear it if use language that appeals to them and their humanity instead of pushes them away.
