Absolutely not, your connection of the terminology is what is nonsensical, and my post merely points that out. Because someone chooses a terminology to use as their own is their own choice. The people who originally meant that terminology to mean something else are not responsible for someone using it for something different - unless the copyright it and then allow its use. Let's use ISIS as a comparative example - a very nasty group - well, they use the Islamic term Allah Akabar when they kill people in the name of Islam. Now, we have establishment politicians falling all over themselves - literally going nuts telling people that this is not Isalm - even though Allah Akabar is a term that is very central to the Islalmic religion. But here you are saying that because some nasty group co-opted a different term that was created by someone else for an entirely different purpose and meaning - that term's use becomes permanently tainted by them touching it. That, my friend, is a logical fallacy.
Your rebuttal fails as the term 'Cuckservative' is used only by a very small, politically homogeneous group. Furthermore, it is not a proper English word, but slang; so it does not exist elsewhere in the English lexicon. With "Allahu Ackbar", those are standard Arabic words, so every Arab knows them, if not the two words combined. Furthermore, that phrase is much like "Praise Jesus", so it's taught and used by a huge number of Arabs (and Muslims), so it is not a rare term found only used in small groups.
While it's possible that the term "Cuckservative" could be found elsewhere, using it in the manner developed by Stormfront and it's ilk shows either incredible luck to have recreated their exact same use or, more probably, someone whose associated (knowingly or not) with those that use the term. Keep in mind that the Free Republic is riddled with moles from such places.
But then, to top it off, the response has been outright scorn and hostility to a friendly 'heads-up'.
I thought it first to be a lack of knowledge on the matter, but the rapid and rabid response that never once acknowledged the information as intended; coupled with the distractors designed to muddle the issue has made me reconsider that point of view.
