Rather than spamming irrelevant articles across the forum you could add some extra information or thoughts you have on the topic it discusses. That would make more for a discussion than simply posting a line and a one line follow up.
There's also a
press board where you can post links, but only reserved for "Notable press hits".

Though to answer the question in the title - no - Bitcoin is a threat to all fiat currency and always will be as it is superior. No form of fiat currency will ever be a threat to Bitcoin. They will try to attack it, as they have hundreds or even thousands of times...but they will never beat it.
