Tim Farron has not done any kind of U-turn. What you have to realise is that not all religious people want to wear their faith on their sleeve or to use it as a means to gain votes.
Some religious people like Theresa May or Tony Blair keep referring to their Christianity as a means of establishing their credibility. What they are trying to say is "I know better than you, I read the Bible, I go to church, so what I tell you must be right". Then, as often as not, they tell you a pack of lies.
Tim Farron is not like that. He is both a genuine Christian and a secularist. He considers his religion is a private matter and nothing to do with politics. He does not preach or prosletise. He does not claim to be an expert in theology and is unwilling to make religious pronouncements. That is why he was reluctant to get drawn into this line of questioning, which he has hopefully now closed out.
I can tell you, because I have met Tim, along with so many other Liberal Democrats who are diverse in every way, all ages, races, backgrounds and sexual orientation, that no-one could ever accuse him of homophobia, or racism, or any other kind of prejudice. He is a decent genuine person, perhaps unusual for a politician, but that is surely good.
All this stupid line of questioning, never addressed to Theresa May or Jeremy Corbyn, is just mischief making by the worst elements of the media. It should not be about selling newspapers or steering their readers away from a politician who has important things to say. Let's hope they move on to address serious issues which Tim and the Liberal Democrats are raising for the good of the country.
