Yes, of course you’re right. One needs to be careful in Bangkok ,though, when visiting temples/wats....you might end up in one run by the loony monk charged with kidnapping and torturing police officers, or the one with the drugged tigers ( there to be petted by the moronic Khao SAN Rd brigade, prior to being disposed of and sent to China for making “medicine”), or those run by the drug dealing, private jet monks, etc, etc, etc, etc, etc.
Stick the the main , better known ones and there is a chance you might encounter something genuine.
