Firstly, either you're seeing bad doctors, or you have a seriously warped perception of how the doctors are approaching things. I work in general (family) practice, and see far more children and adults with viral infections that I give symptomatic advice (and often a certificate for work) than I do apparent bacterial infections that I give antibiotics for. I do have a lot of people ask for antibiotics where I think it's unnecessary, and they don't get scripts.
Secondly, I don't answer questions via email for a few reasons. Most email is not secure enough to meet the standards required for confidentiality/privacy (although a lot of doctors are using specific, approved secure email systems to send letters/reports). Legally I could be on "interesting" ground if I gave you advice regarding a condition without seeing or examining (as appropriate) you. Finally, with the system in my country I get paid exactly nothing for any time spent on emails - which would be in addition to all the unpaid time I currently spend fielding phone calls from patients and other doctors they may be seeing, dealing with paperwork, etc. Mercenary I know, and I'm happy to do a degree of work that's unpaid, but emails would add significantly to it and add in other concerns.
