First, your point implies down votes are a check on bad behavior as opposed to a form of disagreement. I suspect many users use social media voting for a variety of different reasons. Secondly, there are two solutions to that problem: 1. If you believe the environment, group, or social body of a particular conversing venue is heavily biased, whether deliberate or not, you don't have to participate there. Simply leave. 2. If you believe a particular user is deliberately exercising some form of bad behavior or displays an inability to follow the conversation you don't have to reply to them. Simply let it die. For example: whether or not I ever liked or voted for President Trump I would never spend time on Reddit at r/theDonald because I know conversation there is biased like a form of cult worship. Why bother conversing where you are not allowed to disagree on any matter?
