Not true.
A very poor argument such as the one I point out above - is well known to "not work".
Christ gives a great example of making a strong logical argument with his hostile-audicence enemies in Matt 22 for the future resurrection and also in
Mark 7:6-13 with his opposers regarding their bogus traditions that are in opposition to the Word of God. In Matt 22 Christ's stellar logic "silenced the Sadducees" as the Pharisees themselves admitted.
Your claim that we could be equally as successful making statements that don't make sense -- is one of the things you find on the internet where Atheists hold those things up for ridicule and use them as effective proof on their side that to be a Christian is to abandon reason. They gain many converts with the help of Christians.
A great many atheists have become Christian - including one reading this thread - and they did so because of issues like #1 in the OP. But I have yet to find even one that claimed they came to be a Christian while Atheist because of the force of the statement "I don't think my atheism is giving God glory".
===================
Peter says not to give lame arguments.
1 Peter 3:15 but sanctify Christ as Lord in your hearts,
always being ready to make a defense to everyone who asks you to give an account for the hope that is in you, but with gentleness and respect
Paul agrees.
Titus 1:7 For the overseer must be beyond reproach as God’s steward, not self-willed, not quick-tempered, not overindulging in wine, not a bully, not greedy for money, 8 but hospitable, loving what is good, self-controlled, righteous, holy, disciplined, 9 holding firmly the faithful word which is in accordance with the teaching,
so that he will be able both to exhort in sound doctrine and to refute those who contradict it.
It does not say "able to contradict those who contradict" but rather "able to refute those who contradict". In some circles merely name-calling and contradicting is "enough" -- and is all that should be asked of them in their own POV. Scripture does not agree.
