What has a natural species of animal got to do with a religion/ideology/cult? I have never seen a pig making a terror attack!
BTW, it surprises me, how many Gentiles uses pig related words to mean dirty or bad, or to insult. It would be understandable if Jews said it, since pig is a ritually impure animal for them. But some Gentiles are always mentioning pigs as dirty and evil and, not only eat pork but are even surprised or upset when Jews reject it.
