To me, it is very personal... this presidents agenda, his tactics, etc... he is trying to water down MY country. I would have no problem shaking his hand, being polite, then telling him I DID NOT VOTE for him nor do I support his ideals. Hey- it's America, we have a lot of different views. I am sure he is used to hearing negative feedback as well. I feel I have a duty to my country to tell the truth. No disrespect... I would politely tell the truth. I would be careful how far I went due to the secret service being near by.
