I have to respectfully disagree bro.
And I will be very precise. Not in the mood to write lenghty reply at the moment so just couple of points:
Being Harsh is not equal to being an enemy. e.g: sometimes parents have to be harsh on their children in disciplining them. They mean well for the kids and not because they are their enemy.
If you prefer to be the enemy of some particular people, how are you going to convince to accept the faith. You will fail to even communicate with them. Disliking or not approving certain behavior or faiths (answer to kchughtai sahib here too) does not mean you are enemy of them.
