No, you probably aren't to take that statement that way since the statement never said any such thing. He said "most meaningful" which necessarily implies that there are other meaningful things, just lower in a hierarchy of meaningfulness. Respectfully, you seem quite bitter by reading into what was said, perhaps some introspection about the reason for this reaction would be in order.
Bitter defined as 'a sense of unjust treatment', is absolutely correct, but 'angry, hurt, or resentful'... nah, none of that.
In fact, quite the opposite, I'm extremely happy about my decision to not have children.
I'm just not a fan of people who think that it is the most meaningful thing I (or anyone else) could ever do.
In any case, even if one thinks so, I find it quite rude to say that having a kid is the most meaningful thing you can achieve to someone that may not have children ...
I've known people who've dedicated their life to doing charitable work for low pay, it's extremely fulfilling in a way that I will never experience, but I don't get upset when they say that it's the most fulfilling thing they've done.
Remember, their original statement was "Kids are the best, most meaningful thing you will ever do. Its worth it to keep trying." whereas really they should have said something like "Kids are the best, most meaningful thing I have ever experienced. It's worth it to keep trying."
Heavy dose of "in my opinion..."
Kids are absolutely the last thing I've ever wanted in my lifetime.
Am I supposed to take your statement as I'll never do anything meaningful?
Come on.
