If you read up-page in some of the other threads you'll find some right/libetarian people who are also against Trump because of how he's pushing us into authoritarianism.
Yes, right libertarians often oppose right authoritarianism, but that doesn't transform support or opposition to right authoritarianism to something that has no left/right valence.
Well yeah, in a consensus-based process you have to accept that not everyone is going to agree with you all the time. But you do have to try to push forward on things where there is consensus. There was a county committee that had a libertarian on it who would often advocate from a libertarian standpoint, whereas the people the committee affected were often more left/collectivist. However, he found himself briefly aligned with the rest of the group when a county official tried to do something that was against the law.
"Left/right" is always at best an approximation, because the space of political ideology is multidimensional, and because differences in praxis (how to achieve the goals set by ideology) will often be as signficant in people's support for or opposition to concrete regimes as differences in ideology, but the Trump regime definitely is suppported much more on the right and opposed much more on the left.
