Is the term gammon racist

It seems I have moved from a left wing Pinko to a Gammon.

I doubt I will have sleepless nights over it.

There is a huge difference between called something racist day in day out to been called a Gammon in general terms.
The fact that this is even being debated shows how pathetic and nasty this social media driven world has become. Sad beyond belief, give your heads a good shake.
