I asked on Twitter if I can join a certain party despite not being British and a woman not connected with the party in an official way replied that as long as I am eligible to vote it should be fine. I replied that as a German citizen I am eligible to vote for certain elections but not all of them.
Her answer was that she doesn't agree with non-British citizens being able to vote but as long as I pay my tax I should have my say too. I looked her up and I am not being racist but she clearly has a migration background herself and should be more open-minded to other nationalities living in this country.
AIBU to be angry and upset at her comment?
