Cmon. Say something constructive about the OP's work. Event 'it sucks' would be acceptable but nit-picking on title of the post is not good. Let OP know that his/her title is inappropriate or sexist, but please also help OP by answering the his/her's question

Should I change it to say, "So easy a caveman could do it," or would that be too offending to the caveman stereotype?

As opposed to say, younger people more familiar with technology.

It's a humorous stereotype, not everything is sexist.

It's a sexist stereotype, not everything is humorous. My mother read her first core dump 40 years ago.

Seriously? If this was about something physical, then yeah definitely. But just because it includes a woman, it's sexist? Because I've never heard of an "older women are bad at technology/moms are bad at technology" stereotype, but the genderless equivalent is pretty popular.

And if we're going off of anecdotal evidence, neither of my parents are technically inclined. We're not all privileged enough to have multiple generations of experience with technology in our family, let alone computers.

> But just because it includes a woman, it's sexist?

No. It's sexist because it assumes something about a group of people based solely on gender. Or it can be also an example of ageism if both gender and age are involved.

But let's forget it for now, there's another problem here and that is the title is just poor writing. If the author aimed for comical value, then he should have used someone who certainly wouldn't want to create a website. A cat would work. Caveman, too, really. That's because being comical in this case is based on a sharp contrast - it's hard to imagine either a cat or a caveman building a website, and images we tend to see when trying are rather funny.

By using someone who could want to build a website, and someone almost all people have deep connection with, you're just dividing your audience into two groups, those with "website making" someone and those without. What do you think is to gain from such a division? Maybe a flamewar, at best.

Either way, whether it's just poor writing, poor marketing or sexism, it's still counter productive. It attracts bad kind of attention and encourages off topic rants. Don't do this. If you're (the author) not skilled in writing enough, just find a copywriter who will write the piece for you. Or write it yourself and send it to all your friends asking for corrections. There are ways of avoiding outcome such as the one in this thread - I see no rational reason why you would rather write something unknowingly controversial and detrimental to whatever you want to present to people.
