FUD? Tell that to the VVS squadrons flying SU-25s in Afghanistan. These were extremely robust aircraft similar in many ways to the A-10. Facing the Stinger, they had high casualties, forcing them to bomb from higher altitudes and use PGMs instead of strafing and dumb bomb attacks. This was 36 years ago. MANPADs have gotten better in this period.
One was taken down by 12.7 mm ammunition. Clearly the Su-25 was not an extremely robust aircraft. It even has turbojets (hotter exhaust than turbofans) that are completely visible from the ground. A bit of armor around the pilot doesn't make an aircraft equivalent to an A-10.
