“Same sex relationships are unnatural”

This is a BELIEF. Beliefs are what people think is true or false. For example a common belief is that there are only two sexes: male and female. In this example, this belief if often correlated to negative attitudes, but there are also people who believe that there is an “order of nature” but who are still OK if some people don’t follow this “order”. As a matter of fact, this might be the case for a majority of LGBTQI+ friendly people.
