Please explain why is it that paxil (paroxetine) is always linked to birth defects?

The risk is small: Actually, according to scientific research, but is magnified by the legal community (imho). However, that's tough to buy when it is your child that may be affected. Here's what the mayo clinic has to say on the subject: http://www.Mayoclinic.Org/healthy-living/pregnancy-week-by-week/in-depth/antidepressants/art-20046420. Good luck!
