This, logically, is meaningless. If you wanted to make a logical connection you could say "Every Christian is a sinner, therefore Christianity is a religion of sinners. This would be true.
You could also say "All Muslims must believe in the Koran. The Koran requires murder or subjugation of non-Muslims. Therefore all Muslims believe in murder and subjugation of non-Muslims". This would also be true.
It would seem obvious that a religion based on murder and subjugation is not a "religion of peace".
Thank you for making my point. The original statements were meaningless. One cannot judge a religion based on the actions of its adherents, unless you consider Christianity violent because its adherents have killed in Christ’s name.
And note that your syllogism is logically valid, but not necessarily true. Many would take issue with the minor premise.* Therefore, that is the point of debate to be addressed.
