You're not a dummy!
Users of GMRS should never feel that they are somehow inferior to hams. I've seen some really stupid hams and I know some really smart GMRS people. There's shouldn't be a comparison. The two services were created for different reasons. GMRS is for facilitating activities. Amateur Radio is for learning about and extending the use of radio. Both are valuable for emergencies.
The stated purpose for GMRS is as follows:
§ 95.1703 Definitions, GMRS.
General Mobile Radio Service (GMRS). A mobile two-way voice communication service, with limited data applications, for facilitating activities of individual licensees and their family members, including, but not limited to, voluntary provision of assistance to the public during emergencies and natural disasters.
The stated purpose for the Amateur Radio Service is as follows:
