Italy does not recognise Hinduism and does not allow temples to be built and you say they allow conversions? Who are you kidding?
India has much more religious freedom even with the anti-conversion laws. Anti-conversion laws does not prevent voluntary conversion just that its meant to prevent organised conversion activity carried out by missionaries.
The topic here is "religious freedom" and Italy has none at least for the Hindus.
First, "conversions" don't have legal standing, one way or the other, in Western countries. The discussion of inability to convert was in the context of an academic discussion and there seemed to be only one academic who was the Hindus' bete noire. In fact, the article seemed to be written specifically to rebut the arguments of one academic and then to paint the whole country with his opinion.
Second, Italy is the least of countries that would forbid the building of temples. In any case, I was looking for verification for the HT article and I could find none.
