I should stop giving a fuck about people who find certain words offensive.
I do give a fuck about people watering down the meaning of some words, like calling someone who insists on certain grammar as a nazi. That is offensive, the definition of a nazi should never be minimized.
Other than that, fuck, cunt, prick, arsehole etc.
Fuck it.

I lost a dear friend to brain tumor - my sincere sorrow for your friend.

As for the F assortment - gave up most years ago - the rest fell into place along the way !
