I don't see a line. Though if there's an element of humor I see an orthogonal anti-line that will annihilate any attempts at line-drawing.
I'm sure you could find a name that if not met with indifference or a laugh would elicit from me an eyeroll or a statement like "come on, that's dumb" or maybe "that's just asking to derail conversations" but I don't think you could 'trigger' me into a fit. (Of course you're welcome to try via email.) It's just a name.
Point taken, but the original point was being associated with the name, not throwing a fit. Having it on your CV/resume, for example. Potentially alienating clients because of words that stand out from the page in the wrong context. I can see a problem.
The point I responded to was maybe we should be above politics in names, to at least be capable of treating names with a professional indifference. To that end there's a simple test to see if someone you're considering working with believes that too. (Of course it's fully reversible, maybe the future will require passionate condemnation of names that might give offense in order to get hired.) For your point of unsavory associations, sure, but it depends on your expectations for audiences. What's the cost of association if no one throws a fit? What is alienation over a word if not a fit?
I can see a problem if you expect to pay that cost frequently when you bring up the word, and thus avoiding it, but if that's really the case it's worth wondering what other sorts of issues will come up that you don't expect when deciding to take the chance of alienation cost. If I made something as awesome as Stalin I'd put it on my resume, even if it resulted in periodic emails/comments about how insensitive a name it is. Even if some tech readers won't want to work with me because of it, I wouldn't want to work with them, so we're both happy, and we find that out before we actually try working together. I wouldn't put a 'I made Stalin' bumper sticker on my vehicle though. For a name like Kotlin, I really doubt Ukrainian programmers would be upset over it, it seems so absurd, but I can see the possible issue of the general public being sensitive about it in which case it's wise to only have the association in tech contexts.
