If the point is to get them to answer or reason about the topic, then I think we should reject the statement that "there is no polite way of asking." We should find a way of asking politely, such as teaching them to process our questions instead of answering with cached thoughts. Being offensive doesn't win.
I also think it's a poorly phrased question, since it's easily brushed off with "yes/no", avoiding any of the deeper implications in an apparent effort to make it catchy and instantly polarizing.
If the point is to upset people, to feel righteous, or to signal tribal affiliation, then go right ahead.
Being offensive doesn't win.
This is not universally true, but I would support trying to create nonoffensive ways to deliver the message - the combination of direct and conciliatory methods is probably more powerful than either alone.
