Disagreement is not hatred.
I can disagree with you, it doesn't mean I hate you.
It does, however, imply that I respect your person and position, and bring proper arguments concerning my own opinion on the matter.
I have no problem with disagreement in a civilized society. Disagreement can foster new ideas that are a benefit for all. What I have a big problem with is blind stupidity and the refusal of considering that one's own opinion just might not be the Lord's Gospel.
