Your examples are not really comparable, mostly because of context. If someone at a party mentions SSL casually and you feel the need to explain that SSL is dead and they are really talking about TLS, you're just annoying. If someone presents themselves as an expert and says that SSL is "fundamentally broken", it's pretty reasonable to question their expertise. Especially when they actually aren't even talking about TLS but about CAs and PKI. To make an absolute statement about the fundamental soundness of PKI and then use completely the wrong term? Come on. Can you imagine a real expert doing this and not at least recognize their own mistake? Don't talk about "fundamental flaws" when you don't know the difference between SSL and TLS and PKI. This is very much like someone trying to criticize the design of TCP/IP and not knowing the difference between an IP address and a MAC address.
