Atheists bash Christians because they do not understand what a Christian is. Their idea of a Christian is the American warlike neo-conservative nationalist who focusses on the Jewish part of the bible, and almost not at all on the Christian part.
Christianity at its core is a very liberal religion, the new testament is full of statements of rebellion against elites and the irrational beliefs of the old testament. It is a book which praises openess and is against nationalism (It was against the idea of a chosen people). Lastly, it is full of pro-social messages, the opposite of the libertarian ideology of the neoconservatives of the US.
I think a lot of Christians (primarilly American) and atheists have a very incorrect view of Christianity and the early Christ cult movements that started it. Too many people do not understand the bible is from the Roman era, an era where fable was the key story telling element - and instead they see it as history. Another factor is that most of the bible was cut as heresy by the government and Bishops under Constantine I. In my opinion, the bible should be read from a secular standpoint, as a book of fables; not as a history. I don't believe Jesus was a real person, but a character; a personification of the idea of removing beliefs from one's mind, and becoming a more open and caring person.
I also do not believe that the old testament should be payed much attention to in Christianity - it is not that type of religion. The old testament came from a Jewish nationalistic history - they are the chosen people by their religion; whereas Christianity is based on mystical and Hellenized philosophical Jewish thought.
I describe myself as a little dose of toxic masculinity.
