Doesn't Seattle 2072 mention Knight Errant is aiming for a better image when it comes to racism than Lone Star had? One of the main NPCs in season 4 is a 10-foot KE troll, after all. Sure, there's plenty of racists, but you're more likely to get heat from the cops over being Awakened than for being a troll or orc, so I think you're taking things too far - farther than the source material supports, at least.
I'd have to disagree, some of the character creation material over the 4th ed times was.... suggested in my mind some very bad attitudes towards trolls, orcs. In some cases, the language really suggested that it was deserved on some level. Of course I'd say it came about from a self fulfilling prophecy, that because they're seen as criminals, they end up as criminals and the smart criminals prosper, becoming known for being successful criminals, ergo, more trolls are seen or believed to try crime as a means of gaining status, success etc. I believe some of the material from the Shadowrun 4 core book is pretty harsh towards them.
I'm personally not that big of a fan of that level of discrimination unless race relations happen to be an important part of the story you're telling. If it's just a rider to the main story, I probably wouldn't be a fan.
With that said, as long as you have basically taken these passages:
In short, of my cast of NPC's, I have a number of people who will react badly to them. One will not deal with them at all. End of statement. In her case, she dislikes trolls so much she doesn't see anything wrong with turning the tips of the last trolls horns into earrings for her to wear. Mind you, said troll also cost her an arm in the attack. Still, nasty we can agree.
Other parts do include possible lynchings, not lethal, but certainly painful, they're going to be facing a lot of scrutiny from Lone Star, Knight Errant, even with a legal SIN, they will get stopped and pulled in on a regular basis. Any cyberwear they have will be scanned and checked every time they pass through a major border. Any sort of bioware gets detected, things will get interesting for them.
...and distilled it in a way that is explainable to the PCs that are planning on playing those races, I think you're okay. Your idea of "pretty severe racism" and their idea might be different, so it's probably better for them to have an informed opinion before they settle.
I have been pretty clear with the group in regards to race on this front, if not saying on some level, this applies to everyone, regardless of what race they choose. Someone, somewhere, will not like them. Trolls and orcs have worn some pretty severe racism and for most, it's well deserved. Humanis is not the only group out there that has openly racist agenda.
I do plan on a little speech at the start, saying that what they are going to see are that people will be people, with all of the good and bad habits. They will have the pleasure of some people's company, the misfortune of others.
I've also made a point of saying that there's going to be down time, use it. Have a plan and do something, keep your self busy. One of my potential players wants to study magic and run their own street clinic. Another wants to be an assassin. Part of this really does tie in to what I want to do with their world, they have the chance to do some real good, build support networks and reputations for themselves as being something other than a Runner.
In my mind, also gives them something their character would do if they want to retire them, which is something I want to offer, considering how this campaign could go.

It's not going to be every session, every second, third. It's going to come up when dealing with some NPC's,
In terms of the type of racism, I was going to try and keep it to species lines, that since dwarves and elves are the most 'human' of the metahuman types, they don't get it as bad, if they get it as bad. Orcs and trolls look the least human, most obviously not-human and so the most severe reactions.

Running SR5 and just planning on the basic races. I was going to keep it really simple on this front, as much as I could do to keep it about the players and what they do, how they choose to do it.
