Which again gets back to the point that it's crucial to turn the brightness up or down to match the ambient lighting when reading on an LCD or other backlit screen.
Just like with paper or e-ink it's crucial to have enough light--and not too much (especially if it's bright white paper) to minimize eye strain.
Any type of reading can strain the eyes, the key is to get the ergonomics and lighting right to minimize eye strain, and from there it's just a matter of what each person prefers and what feels best to their eyes.
I do think a lot of LCD haters have only read on laptops or desktops, which isn't really a fair way to judge LCD screens for reading as they 1) probably didn't adjust the brightness and 2) Even if they did, it's near impossible to get the ergonomics right for reading in terms of distance from the eyes etc. vs. using a tablet that you can hold and read just like a book or e-reader.
That said, it's again a matter of what people prefer, but people should be softer on bashing LCD reading if they've only done it on computers and not tablets, PDAs etc. that can be held properly, easily adjust the brightness etc.
And I'm not saying that everyone who hates LCD has done that and is "doing it wrong" etc. It's just not that many people have owned PDAs, Tablets etc. as reader devices, and I don't think there's really a "right" way to read on a laptop, netbook or desktop as the erogonomics/form factor are just terrible for prolonged reading.
The only way to really make a fair comparison is to read on a book for x hours one day, then an e-ink reader for x hours one day and an lcd tablet for x hours one day and compare your experience. Making sure you read in the same positions and adjusted ambient lighting properly for the first two and the backlighting is adjusted properly on the lcd tablet.
Otherwise, one can't really have an informed opinion on what works best for them if they have tried all 3 and compared them for themselves.
For me, Paper books are best, e-ink comes in second, and LCD tablets (iPad) are a close 3rd. But it's all close and at the end of the day I'd go with the LCD tablet as I don't do prolonged reading all that often and would rather have all the other functionality over the e-ink screen and long battery life.
