I don't think its necessarily about the culture itself here, its merely a cheap populist tactic to rabble-rouse among a nation that has a rich history and struggles to handle the fact that its present isn't at that zenith. France do a lot of this sort of thing too.
I would argue that belittling cultural preservation demonstrates deep Anglo-centric bias. While its fine for lulz, I worry that you're being sincere. Try asking _anyone_ who doesn't have English as their first language in a serious context how they feel about their language and you'll struggle to find someone without a genuine fondness for it.
On paper there is absolutely nothing wrong with cultures seeking to preserve the use of their own language, however it is fair for us to argue that restrictive and punitive measures such as this are not helpful.
Bear in mind one day English will no longer be the lingua franca as demonstrated by the word for lingua franca. ;). Would English then be a "relic" to you?
