Of course you don't have to lie, I recon you better being honest!
But as I (a bit off topic) wanted to point out, what I felt weird about your choise of words. Inly humans deserving disgusting-label in my mind are those, who do bad (murder, rape, hate-crimes, etc.) things to other people. I might be sensitive, I admint that cladly, but I don't get offended very easily by simple words.
And don't get my message wrong, I don't mean to put you to that bad people's gategory even if we have a difference of an opinnion. And you do have a right to feel nausea over what ever you ticks you wrong.
