Unironically, the republicans aren't shy of calling liberal opponents 'nazi' either. Do conservatives have any responsibility to also tone down their rhetoric?

Unironically, the republicans aren't shy of calling liberal opponents 'nazi' either. Do conservatives have any responsibility to also tone down their rhetoric? There was a time when the two parties had a very different dynamic and could, at times, work together when a given policy was in line with both. I think this degraded and then the tea-party conservatives broke it for good, opting for a much more confrontational style where democrats ceased being people with a different opinion and started being 'the enemy' with whom no compromise would be entertained. This trend continued, even strengthened into MAGA trumpism. Biden's bipartisan immigration bill for example, which had many components which conservatives wanted, was rejected because Trump thought it would be seen as 'a win' for 'the other side'. I can't think of an example where a bipartisan bill was rejected by the democrats for similar reasoning.
