C# dev here, and I don't bash Java, in fact I don't tend to comment on languages that I'm not an expert on, because well, not an expert. This covers the vast majority of programming languages and toolkits. Nobody know them all. Nobody knows more than a small fraction of them.
I'll make one generalisation though: any dev of $langA that spends their time bashing $langB is doing pathetic insecure gatekeeping. And should give it up. This applies to what grandparent comment is talking about, and to grandparent comment itself.
It's not cool to hate on an out-group, even if it's a community bonding experience.
