Accounts differ, but it seems that he was removed as a Liberal Democrats (a medium-sized UK liberal party) candidate because he supports tightening regulation on access to abortions.

As I say in the article, Popper restricted the tolerance paradox to very authoritarian movements. Moreover, he recognized that broad interpretations of the paradox threatened liberal democracy. In my opinion, liberal interpretations are now too broad.

‘In recent years, there have been extensive debates about liberal (in)tolerance, involving topics such as the right to hold controversial views and the right of businesses not to serve conservatives. Yet focus on individual cases tends to miss the point.

Whilst individual episodes will involve different rights and wrongs, the large number of cases means that irregularities will even themselves out.

There has been a restructuring of liberal incentives. In Western societies, liberal values of dignity and self-expression have become hegemonic, meaning that liberals have fewer incentives to advocate tolerance.

We may wonder whether liberalism without tolerance is credible, ideologies which are stripped of central elements becoming something else. Indeed, social justice ideology seems to have succeeded liberalism, perhaps spelling the end of liberalism as we know it.’
