Why we have a moral responsibility not to criticize praying

Article is solid but thread title is ludicrous.  Eating corn can provide health benefits. This does not, by extension, mean corn's cultivation and growth hasn't led to a plethora of issues as a mono-crop, along with the accompanying criticisms.

As with so many of the OP's threads, the logic is inches deep, the issue itself a chasm.  That a practice can provide positives is by no means an indication it doesn't carry or lead to accompanying negatives. Black/white thinking is silly. 

And yet, plenty of evil deeds have been done by people who pray regularly, like, up to five times per day.

And often, these people claim a moral justification for their evil deeds that has the same source as their prayer guidelines.

Conclusion: We do not have a moral responsibility to not criticize prayer.

And: Prayer is not intrinsically good.

In my opinion we can criticize any action that causes harm. If prayer helps a terrorist to be more focused and kill more people more efficiently, or, as mentioned before, if people pray for their sick children instead of taking them to the doctor, then we have every right to criticize prayer.

The strawman builder strikes again.

Your strawmen certainly are.

I'm not going to refrain from criticising belief in God for as long as religious people still wield both the desire and the power to restrict my liberties. That's not specific to prayer, but to religion in general. If someone's religious, then prayer is just one of their delusional habits and not something that is pernicious in and of itself.
