So this was not an attempt to "atttibute everything to overt politics". Embryonic stem cells, however, are an overtly political issue in the US.
You seem to be exempt from this rule, however:
> why mention it at all other than to muddy the waters by injecting additional politicization to the HN community?
Do you see how you were ascribing unfounded and unproven intentions to someone else for their comment? Your claim that "obviously, they must have done it to muddy the waters" is the perfect example of precisely what you complain about.
There's no argument to "win". After my second comment, I responded to your question. As for "getting the last word in", I only do so to refute the idea that I said you were uncivil. You're right that this is far off-topic now, and likewise I won't respond further.
I continually find it depressing, distracting, and unuseful how quick some are to immediately attribute everything to overt politics. Why some submissions catch on when has so many variables. We're quick to see patterns, amplified by our own biases. Other than skywriting, I'm pretty confident that clouds aren't shaped to be animals or faces. The data for submissions is available via a couple APIs. If you want to ascribe politics as playing a role in this post making the top page now, you can try to back it up with some actual evidence and make your claim substantial.
