Sometimes i think objections towards Minarettes is a "sweep it under the carpet thing" if there is no outward expression of Islamic presence then the Swiss can feel comfy. Hence there are lots of prayer rooms and centers, few Minarettes.
As far as Muslim graveyard's go i understand the Swiss way of thinking, the Swiss cant have a permanent burial place, your loved one is on a contract of 10-20 years of rest in peace, then they must leave the spot to make room for others. If they cant why should others?
