The thing is, right vs left doesn’t necessarily capture extreme positions.

For example, you have r/neoliberal on Reddit. There users are overwhelmingly in favor of YIMBY policies (zoning reform, banning single family zoning, focusing on high density coupled with public transit), getting rid of the Jones act, pro free trade, automating ports, pro carbon tax, etc. while also being very liberal/progressive (imo) on most social issues.

So, while not necessarily extreme left or right, they have views that would be relatively extreme compared to the average voter, namely views on housing and trade.
