Big flyers are possible (whether or not they are "mostly gliders") and for certain applications (fuel efficient long loiter UAVs for example) ornithopters (even "mostly gliding" ones) are probably a better choice than other kinds of powered flight. Furthermore they becoming more and more technologically feasible.

What exactly are you arguing against?

I don't think bird like designs make sense for vehicles much larger than birds. Steal ideas from biology but don't copy exactly.
