GameRager: In order for either to be transphobia or racism they have to be doing so in the proper context: The person disliking trans has to be doing it because the other is trans for it to be transphobia, and the one suspicious of a minority has to be doing so because of the other person's race for it to be racism. Again, context matters and not everyone is x-ist or x-phobic just because theyb dislike a person who happens to be trans or a minority.
A person can dislike something anyone does(even a trans person) without being transphobic, and a person can be suspicious of anyone else for valid reason and not be racist.
In your example if someone robs you at gunpoint and they are black and you are suspicious of all people after that then it's not racism....only if you are only suspicious of only black people is it even mildly racism.
I guess the language difference is popping up again. You said originally 'not liking what trans people do' and 'being suspicious of a minority'.
For your future reference, 'a minority' is not a single person. 'A minority' is a group of people not in the majority. The example you gave was a racial minority e.g. black people in the US. So when you say 'being suspicious of a minority', there's no context involving an individual person. You're literally saying you're being suspicious of the group.
While saying 'I don't like what trans people do' is not entirely synomous with 'I don't like what all trans people do', so it may be not as problematic, it's close enough and avoidable enough, that it would be seen as transphobia.
