Source? In Germany at least that’s not the case, it’s mainly the conservatives who push for it. In the original vote, only the greens clearly opposed it. Later on, SPD (center-left) and FDP (liberal) changed course to also oppose it. Couldn’t find results for other countries though, so I’m genuinely curious.
I really enjoyed visiting Cimiteiro Monumentale in Milan. A historic cemetery with lots of lavishishly designed huge tombs. Very few tourists there and no scammers whatsoever.
