well no, what you train is far removed from muay thai, so much so you could have bolted together boxcercise with goal-kicking and pretty much come up with a kickboxing class- IMO. As you well know 'kick boxing' was created as a sport in the west to supplmenet boxing, so you know my stance, it shouldnt even be considered as a martial art.
4 point striking vs 8 (or 9 point) striking, there is no contest - it isny jsut elbows that are removed, the most effective weapon there is in cq combat - the knee is removed too. There is no clinch game, which is vital in cq. Basically a thai fighter with all these advantages wil make mincemeat out of any kickboxer
You really ought to try a well run muay thai class, and you would see instantly the differences in kicking technique and power, speed, balance in clinch etc. The boxing can also at a much higher level - muay-thai fighters have been boxing world champions too ( payakaroon won the wbc title in the 80s).
Generally though, many thai fighters have gone into kickbxing ruled events and won, very few kickboxers have succeded in thai rules, rob kaman is one but he also trained muay thai as a youngster.
Take a look at this guy and tell me he isnt one of the best stand up guys you have seen
