https://en.wikipedia.org/wiki/False_consensus_effect
In psychology, the false-consensus effect or false-consensus bias is an attributional type of cognitive bias whereby people tend to overestimate the extent to which their opinions, beliefs, preferences, values, and habits are normal and typical of those of others (i.e., that others also think the same way that they do).[1] This cognitive bias tends to lead to the perception of a consensus that does not exist, a "false consensus".
I think you'd be surprised by the survey results on these issues... one conducted by the Australian Population Research Institute showed over half the sample wanted a "muslim ban".
I don't agree with that opinion, but I think most people don't truly recognise where the political views in this country are.
