I normally expect trolls at certain events, especially cheaper ones. However, I'm utterly shocked at the behavior of some of these people at SXSW who are in all likelihood representing a company, and/or paid $1000+ for a badge. The comments that some of the attendees made at this were something I'd expect at a PAX or ROFLcon (due to the price and age of participants), not SXSW.
Also, its unfortunate to hear about how they tried to rope in Alexis.
Having money or connections does not transform one from being a jerk/troll/bigot. It's not surprising that there were such people at SXSW. It is somewhat surprising the panel did not have better moderation.
People with money can be assholes too, and a social media conference with zillions of attendees is a great way to bully yourself into a soapbox with relative anonymity.
