I somewhat agree with this. Huge boobs make me uncomfortable, but I don't feel that way with the image above.
Just remember, a very significant portion of furries probably aren't even into boobs, because from my research, roughly 80% identify as male, and about 30% and 40% as gay and bisexual respectively, and bisexual doesn't mean you're attracted to men and women equally.
Also, if you're interested in women, that doesn't mean you like big boobs.
