Cognitive Dissonance vs Mental Stability

I have noticed a trend among some of my online social circles which I do not like. In fact, I feel it is downright unhealthy and dipping into toxicity. The thing which brought us all together is our similarity in beliefs of a political nature and how our life philosophies inform those beliefs. The discussions held by this circle have been, in the past, a means to teach others while holding reasoned, open debates with those who have clearly opposing views to our own. These debates allowed for questioning from observers and the peaceful exploration of ideas by following theoretical scenarios along tangents to their eventual positive or negative outcomes. There was respect for differing spiritual beliefs and a willingness to support each others' needs based on what tribulations life has thrown at each member of the group.
