[Grammar] being the gentlemen that I am/was?

[sitifan]

For the first time in my life, I’ve become a sports drink junkie. I still guzzle water. But I like how the lightly flavored drink displaces the “workout” taste better than water. So I drink fluorescent colored super juice after heavy training.
Since Powerade (not Gatorade) was on sale last month, I stocked up on all eight flavors. And being the gentlemen that I am, I decided to review them for you. So the next time you reach for a 32 oz. bottle, remember the top 5 most refreshing Powerade flavors, expertly named by yours truly:

In the above passage, what's the difference in meaning between "being the gentlemen that I was" and "being the gentlemen that I am"?

The writer is making it clear that he was not just a gentleman at the time he decided to review sports drinks for the readers; he is always a gentleman.

If you're still a gentleman, use 'am'; if you're no longer a gentleman, use 'was'.

And it should be gentleman not gentlemen.
