Pierre LebelJohnney,
Just like of us I guess, at some time during a gathering of friends, you expressed your opinion about some political issues. Were you required to display a membership card of one of the existing political party to do so? When we express an opinion about something, there is always a reason for doing so. And one reason is probably to try to educate someone on the topic, declare your position on the subject and may be to influence them. Anything wrong with that?
The fact that one suspects that this is done for a reason that one does not like or does not agree with does not make it reprehensible.
