I have something to ask. Do the English(Londoners in particular) citizens with right wing beliefs and those with left wing beliefs get along very well with each other as compared to Americans? I don't mean those with extreme right or left beliefs.
I only went for a holiday there once so I don't know what their attitude is regarding political beliefs.
Agree with the comments made by Bhillyard and Strong In Him have. Politics in Britain are not as polarised as America (or at least, as reported). Except for Brexit. I carefully said 'Britain', as Northern Ireland is different.
In most churches, you are likely to find people of different political persuasions, or none (most common?). When I first started attending my church (Baptist), one member was a leading Conservative local councillor and another was a trade union official (Labour).
There are some important differences compared to America. Britain is no longer a Christian country, not even nominally. So, that means that the political parties are not particularly interested in courting the 'Christian' vote.
There is no equivalent of the 'Moral Majority' in Britain. While Christians are involved in politics, I am not aware that there is any correlation between a particular denomination or theology and with a political party. If a church minister or leader were to offer public support for a particular party, they would risk antagonising the majority of their congregation or membership.
Christians are involved with issues, but I think we have a much wider range of concerns than the Moral Majority. Few people will vote for a party purely based on its stance on one or two 'hot potatoes' such as abortion or same sex marriage (besides, in England, the three main parties are very similar on these). Other issues include: poverty, injustice, climate change, debt, human trafficking, modern slavery, homelessness.
