I can't confirm that. I grew up learning blackletter first (since my mother didn't want me to get bored in school too quickly) and after a few minutes of getting used to it again, it's not at all harder to read to me than modern writing. Some letters, like the ſ, aren't that easy to get used to, but when you do get used to them they actually help you (or, well, help me) read faster. That is, I think, because letters with an ascender are easily identified, and ſ (a different form for s) is actually very common in those texts.
