Antichrist?
If you live in a country where you have freedom of speech, and freedom to vote, and freedom to participate in politics...
then it is both your civic right, and your civic duty, to voice the opinions of your conscience.
So dislike, disagree, complain, all you like, that's perfectly fine.
The "right" is all for free speech.
(It used to be the left also... but that's changed.)
However, if you want to come on a Christian forum, and claim ANYONE is the antichrist...
you'll need to support that with some scripture.
