They cannot call themselves muslim or their faith as islam. If they do so it is freedom of expression in your "civilized" or "law abiding" world. And if some one stops them under constitution then he is spreading hatred?

There are two paths: one is knowledge (ilm) and other is Love (Ishq)
If you look at it with latter you'll find this is no hatred but commandment.

Ishq Pe Bijli Halal, Ishq Pe Hasil Haraam
Ilm Hai Ibn-Ul-Kitab, Ishq Umm-Ul-Kitab! (Allama Iqbal)
