I've seen people getting a little snarky about piracy viability, but the others surprise me. Not wanting to stir anything up, could someone PM me with brief descriptions of why people got agitated over the other issues?
I'll point them out, as I see them, and attempt to be relatively neutral, here...
The Lesbian Aslan issue has died out, but was based upon a very well written but highly controversial aslan fan-expansion that involved making Aslan females genitalia more hyena-like (and thus less readily apparent what gender is by genital configuration), and solving issues with aslan gender ratios.
Near-C Rocks and World-Killer shuttles: The issue is triggered by Traveller's constant thrust drives; it's readily possible to get up to 0.1C in under a week... at which speed, a shuttle is a huge bomb. Assuming, of course, that you don't miss the target world. This honks off a number of people for a variety of reasons: the drives themselves violate thermodynamics, no sane government would let civilians fly ships that can wipe out civilizations, etc. Been a recurrent flamewar starter since 1995... on the TML, and later, here... usually when someone thumbs their nose at thermodynics, followed by someone else accusing the pro-thermodynics person of not playing Traveller, followed by other snark.
The piracy issue is hot and multi-fold. The following groups seem to be pretty stable:
1) Piracy exists in the OTU because MWM says it does. Now we need to figure how
2) Piracy Can't exist because there ain't no stealth in space
3) Piracy won't exist because no sane government will let civilians fly spacecraft with gravitic drives
4) Piracy won't exist because there's no market for it
5) various means of making it work by using more inclusive definitions of piracy
6) "Won't you all just shut up about it?"
Groups 2-4 all get frustrated with group 1, often leading to snark when group 1 cites canon to refute them, and with group 5, claiming barratry and hijacking aren't piracy.
Group 6 tends to be the response to the snark and cross-chatter, not realizing that all they're doing is peeving off everyone else in the discussion by essentially claiming that noone in the discussion has anything valuable to add. Which, after 15 years, really, I've not seen anything NEW added, myself.
