I don't know what country this article is referencing but assuming it's a sourced, empirically supported article (It probably isn't, lmao) I doubt it's the USA. Demographically speaking, the US is becoming less religious, more urban, and the racial gap is closing, rapidly. The USA is gradually becoming more multicultural, and let's not forget that in the last decade or so, sport for same-sex marriage, social rights, etc., has ballooned. Gay Marriage, as an issue, arguably sunk John Kerry's Presidential Bid in 2004 but reinforced Obama in 2008, and 2012 and in the midterms since so I really don't get the logic here, because I don't see a serious study or definable trends. All of those things do not make for a more conservative society. Do your research before you post.
I don't think that's a fair assessment on the OP. Certainly social movements can occur and gain steam in spite of and in reaction against the mainstream trends. The study being mentioned might be taking note of a movement that's just beginning to get on a roll - whether for certain nobody knows - but it's precisely that nobody saw it coming that makes it so novel. And the study is about Generation Z, which is just beginning to be politically socialised and so far cannot even vote - perhaps haven't even taking American Politics as a high school course, so based on your criteria for what signifies political influence, of course you're not going to see any trends. Lastly, the OP and the study itself is about specific generations and not about the overarching trend in society so it's not fair to suggest that the OP made a claim about that either way.
