It is at best unnecesarily antagonistic. The way it’s written will never bring anyone to your side. But e see this in almost every apologetic piece Roman authors write that are posted here. And we’re told of course that isn’t the case.
The Real Presence is either true or it is not, so only one interpretation can be correct. The Church has maintained that it is true since apostolic times. It is not antagonism to point to one’s brother to the truth, but, rather, an act of charity (in fact, one of the spiritual acts of mercy). Please consider and pray about this question with an open heart. The Eucharist has led many Protestants to the Catholic Church.
As to your question about whether I am aware of the denomination you belong to: no, I am not aware, but assume you are not Catholic or Orthodox, because of your position on the Eucharist.
