From my understanding the new law will require intent.

If the posters intent is simply to stir up hatred towards muslims then yes it's mean, (s)he's a bigotted bas**** and in the future (s)he could be prosecuted.

However, we don't know his / her intent.

We're all used to free speach we need to be very careful about what we dissalow.

You have a choice, ignore it and it will go away or make a case against what is being said.
