Weak people need something to believe in. Weak people like to be led rather than taking their own actions. Weak people are afraid of what will happen to them afterlife. Weak people are easily brainwashed. Weak people are perfect candidate for zealots, leaders, or prophet.
So yes religion does matter.
Nice try. No one likes to be called "weak", so it would seem to be an effective slam.
However:
All humans are weak. That's why we easily fall into temptation, and why we depend on pride to carry us thru.
Admitting our short comings and overcoming pride, peer pressure and mockings requires strength of character.
II Corinthians 12
9 And he said unto me, My grace is sufficient for thee: for my strength is made perfect in weakness. Most gladly therefore will I rather glory in my infirmities, that the power of Christ may rest upon me. 10 Therefore I take pleasure in infirmities, in reproaches, in necessities, in persecutions, in distresses for Christ's sake: for when I am weak, then am I strong.
II Corinthians 13
3 Since ye seek a proof of Christ speaking in me, which to you-ward is not weak, but is mighty in you. 4 For though he was crucified through weakness, yet he liveth by the power of God. For we also are weak in him, but we shall live with him by the power of God toward you.
Philippians 4
13 I can do all things through Christ which strengtheneth me.
People who trust God and know the teachings in the Bible are the hardest to "brainwash" and lead astray. They aren't afraid of "the after life" or opposition.
It's the people who
don't have a firm foundation in Christ who are easily led by false prophets (religious, philosophical, political).
