This thread shows a lot of ignorance on the part of Catholics if they think that Protestants don’t have communion. We do on a regular basis but not every sunday.
I think the basic premise here that Catholics are saying is that Protestants have "Communion", but the form of Communion they have is not the ceremony that Jesus instituted, therefore it's not really Communion.
And how often Protestants have their communion ceremony varies from denomination to denomination. Some have it on a regular basis. Others have it like once or twice a year.
