If America openly embraced itself as a Christian country, I would not have an issue with the religion. But claiming to have freedom of religion just does not align with making schoolchildren cite Pledge of Allegiance ("one nation under God") or printing "In God we trust" on your money. Or, like they're suggesting in Arizona, making high school graduation conditional to reciting an oath by God. I have not personally felt any sort of discrimination by religion, or any sort of push to Christianity. However, when the religion starts affecting legislation, I think freedom is lost. Examples of this are the difficulty of same-sex marriages, and decisions taken on women's bodies and futures by attempting, for example, to criminalize abortion after rape as "tampering with evidence" as in New Mexico.
And then the freedoms that money brings! There is a freedom for billionaires to buy off media to promote their agenda, instead of freedom for individuals to obtain reliable news. So apparently Fox News provides the biggest chuck of news to Americans, but unfortunately Fox News feeds the masses bollocks about climate change and thinks Germany is sunnier than the US. It's no wonder this country is so backward at times if the "news" are blatant mind control by someone rich enough. I feel there should be a freedom to access news free of censorship and bought opinions (like these) on public TV in the style of BBC.
And I want to finish off by saying that there are many numerous things that America excels in, like freedom of speech. I've never experienced it elsewhere like I have in San Francisco, where anyone will start an opinionated debate with you on the bus. There are many countries that I've been to where I would not dare to publish this post due to government policing the internet for unwanted opinions, but in America (so far) I've felt safe to say what I think!
