oder vielleicht horrible

thanks codero

I meant it more like turning away from someone, quasi in disgust, the person is appaling, although the person is not stinking horribly

one is disgusted by that person, it's not hate

Why reject "loathsome" -- it seems to fit your wishes exactly (at least according to a dictionary...a handy resource.)

Merriam-Webster:
Full Definition of LOATHSOME
: giving rise to loathing : disgusting

You make your own suggestion,too: appalling
Full Definition of APPALLING
: inspiring horror, dismay, or disgust

obnoxious might be rather neutral,
I like feculent but that is probably too offensive.

'Ernsthafte Krankheiten' halte ich nicht für sehr idiomatisch. 'schwer' ist die übliche Bezeichnung.

Ich finde beide Vorschläge in #4 nicht passend. Ich bin auch für #1.


(Am Rande: wo kommt "stinking horribly" auf einmal her?)

repugnant people
or simply ugly people

Würde "ugly" nicht zu visuell interpretiert?

Not if the proper context is given. One can be ugly externally as well as internally.

I might say detestable or despicable; lots of possibililties, depending one's personal feelings I think

I'm rather partial to "loathsome", myself.

I'd go with "loathsome", "detestable" or "despicable". "disgusting" or "appalling" might work too.

another option?

# 4, I don't know if feculent is too offensive, but you'd certainly have most people running for a dictionary :) :)

I've just looked it up - it's about as strong as one can be in this context I'd say :-)
