Re: "For me, its easy to dislike Trump because he is a Christian"

I see no evidence that he IS Christian. 

He bears constant false witness. He has committed adultery numerous times (and quite publicly). He covets ... a LOT. He mocks Christian sacraments (and the Pope). He rejects Christ's message to "sell all that you have and give it to the poor". (  I sincerely doubt he tithes.) He rejects the Christian concept that all are worthy. He mocks the disabled and doesn't seem inclined to help 'heal' any maladies. (Quite the opposite, it seems.) The only way he's "honoured [his] father] was to emulate his discriminatory business practices by trying to deny rental accommodations to blacks. He rejects Christ's notion that "the servant is worthy of his hire" by stiffing his contractors. He in no way "love[s his] enemies - quite the contrary. (He seeks revenge for every imagined slight.) He is neither charitable nor loving.

There's more. (Sadly.) 

Pious? Maybe; "Christian"? No way.
