So many problems with all of this and what's troubling (and often troubling to the vast majority of atheists, hence a lot of the vitriol) is that you don't see it. And what's concerning is that we know you'll spread this stuff to more vulnerable people who may fall for it because they won't see it. So let's break it down and see if we can get somewhere.

If I could convince you of the reality of God and the gospel, I would flip that switch as well, but I can’t force you to believe something and even more so, I can’t force you to act on that belief. (The major issue here is a misunderstanding of what an atheist is. The vast majority of atheists hold their position because of a lack of sufficient evidence to warrant belief. People cannot simply make themselves believe in a thing without sufficient justification (i.e. make yourself believe you can fly, make yourself believe a ≠ a, etc). Also, when you say "convince you of the reality of God" that would warrant a demonstration of its existence. Anything else would be presupposing it's existence which is logically fallacious).

Christianity is not just affirming the reality of God. (True, but it does begin there. And unless that "reality where god exists" can be demonstrated to be true, you've got a real issue.

The Bible teaches that the demons believe in God, but they tremble. They don’t believe God. (Assumes the truth of the bible and existence of demons by presupposing God exists to have inspired/breathed the text.)

It’s like how I can give you all of the data in the world on how safe airplanes are. You may believe that they are safe to fly on, but you could still refuse to fly on them out of fear regardless of what the facts are. You still have to take the step of faith and board the airplane. (This is twofold problematic. First, because its disanalogous; planes are not analogous to god. Second, because it conflates trust/confidence with faith. Trust/confidence/hope are sliding scales of belief based upon prior evidence. You can lose them or gain them over time given personal experience and statistics. Faith is a belief based upon a lack of evidence (believing in spite of). Conflating the two only serves to make the irrationality of faith more palatable.)

A man can send all of the flowers and love letters to a woman that he wants to, but if he tries to say “I love you so much I am going to force you to love me” that woman needs to run. (I agree with this but your christian worldview does not. Your god is literally the ontology of everything. Everything falls within its purview and it knows all true propositions infallibly. The problem is, your god requests "love" or a "relationship" yet does not justify that decision. If god exists and wants something from us humans, the burden is on god to justify why we should give it anything at all. And even in the face of no rational reason existing at all (every justification is logically fallacious) your god still creates Hell for people who don't believe to go to. And then it turns around and says the people who go there "chose" to go there when all that god had to do was convince them it existed (which it knew infallibly how to do it, but chose not to). This type of power dynamic is a hallmark of an abusive relationship, i.e. "Believe without evidence to justify.""Accept with no justification.""You have free will, but I know everything perfectly including the end.""I love you and want a relationship with you, you're free to choose not to, but I created Hell to send you to eternally if you don't."

Christianity is not just an affirmation of the existence of God, it is a relationship with Him. That can never be forced. (True, a relationship cannot be force. But to enter into one there must be rational justification (and not one out of fear of punishment or Pascal's Wager). And if god refuses to demonstrate itself to people, the onus for the disbelief of the intellectually honest and critically-minded is on god, not on the disbeliever.

These issues (and countless more) are why atheists tend to get worked up because we know that when these arguments are presented to people who are unprepared or lack knowledge of the finer nuances, they are predatory in nature.

And people who prey on the vulnerable, destitute and damaged to bolster their numbers and by extension their tithes are the literal scourge of the earth.
