As for ageist, that actually strikes at the heart of the topic. Web facility is absolutely correlated with age. Its defensible to talk about generations and technology frankly.
My point is that the person that has a problem with what they consider obvious stereotyping that's a problem with discrimination has easily overlooked something others would consider an obvious stereotype that leads to discrimination...
If we're going to lambast the OP for being sexist, then this commenter should be lambasted for being ageist. Yet I bet if you ask the commenter they'll say they don't behave like an ageist and would rather not be called such...
yet said commenter doesn't bother affording the OP the same level of discourse or benefit of the doubt.
today's political correctness is full of this sort of hypocrisy.
in my opinion the better option is for people to stop being so sensitive and to look for actual discrimination instead of perceiving it from people they know nothing about based on one line on the internet...
I'm not even saying its a good tagline, I'm simply saying the gendered aspect is unnecessary because if we're dealing with stereotypes, old[1] people get confused by the Internet is far more valid than the inference that it's just older women who are uncomfortable. That's the distinction.
[1] to be clear, I'm not saying anyone not born in Gen X or Gen Y is "old" or less comfortable online.
