Strike Freedom, the gas you added to the open wounds of those who really thought it was utter garbage that Kira survived the destruction of Freedom is old. We're quite used to people rubbing it in that Kira has lost before, therefore he is not some God.
It's a combo of Kira's immortality and Lacus' constantly-superior idealistic speeches (so much like dullindal's i believe, except she has nowhere near the same ambition to lead others) that have swelled the corps of Kira/Lacus Haters.
I know everyone will have different opinions. I loved Kira in the original SEED series. He had flare, was constantly struggling to figure out what to do, showed alot of emotion, was used and confused etc. Destiny's Kira lacks a great deal of these things. and it is getting old, him always using the SF or Freedom's interface to disarm dozens of enemies at a time, then drolling on and on about "doing the right thing".
I don't have anything againt Kira fans, except the narrowminded ones (and there are ones in every character's following), I solely blame Fukuda and the anime creators for using him the way they did in destiny.
