> There is no feasible way to separate politics from everyday life, and leaving "politics to those who knows about it" isn't really viable.
I vehemently agree with the second statement but the first is absurd without further establishing what "politics" means in this context.
> If you have listeners you have a responsibility
Not everyone listens to admire a person or to see your own views approved. On the contrary, I don't think popularity or visibility implies responsibility. That would also not hold up to reality, restrict the dialogue and patronizes listeners.
Maybe try to convince people on the merrit of your position without treating them like children.
