A religious belief is also associated with core values. Either way, the problem with bigots is that they typically misinterpret someones core values. So they may fear Catholics because they think they want to impose the pope on them, or they fear muslims because they want to impose sharia law.
Or they fear Labour voters because they want to make the country communist, or, in Jon1959's case; he fears Tories because of his own interpretation of what they represent. But the Tory manifesto advocated gay rights, fulfilling a referendum result, support for jobs, economic growth, liberalism, all the rest of it.
The overwhelming majority of Tory and Labour voters are perfectly reasonable and good people. To hate them for it is not reasonable.
In my opinion, unquestionably Jon 1959 fits the bill of being a bigot. By his own definition he fits the description perfectly. The difference is, he thinks that his bigotry is acceptable, but then that is also a defining characteristic of all bigots.
