No, I merely pointed out that religious upbringing is explicit about some topics in ways that non-religious one usually aren't.
Your counter argument can be flipped around into "religious upbringing doesn't necessarily mean bad morals & ethics", so in effect it's not really saying anything meaningful.
Not everything must necessarily be a religion-vs-atheism competition (in fact it's tiresome that some people insist on putting every religion-related discussion in that light). I believe I was clear enough when I indicated that I'm open minded to ideas from religious groups, but I don't subscribe to their faith, so I don't understand the insinuation that I'd get brownie points or something for "shilling".
If you're seeing a factual argument exclusively as some sort of attack on your belief system, then you're missing the point that self-improvements efforts shouldn't be discriminating against an idea solely due to the source of insight.
In other words, if a statement is "you don't talk to your kids about morals as much as [insert religion] people do", it's petty to respond by saying "well the religious group you belong to has people that do poopy pants stuff" (even more so if some atheists also do said poopy pants stuff); it's more productive to instead say "huh, how then could I talk to my kids about morals more often?"
The parent mentioned specifically religious believes as a tool for good child upbringing.
My counter argument shows, that religious upbringing doesn't necessarily mean a good moral & ethics.
