“Which basically means that you are trying to restrict someone else’s freedoms.”
Really. The freedom to come into a Catholic church, take the Eucharist surreptitiously, and then hold it and Catholics up to public scorn, sacrilege and ridicule.
Yep. It's unpleasant / morally wrong but it's their freedom. The road you propose leads to theocracy. I'll pass on being temporally ruled by any religious figure.
If Catholics want to make this large of a deal about this then why not take measures to stop someone from doing it? Like having the priest place the host in the petitioner's mouth?
