Well, I don't know.

First of all, contrary to your "No", I would say that "Yes", Moe Greene was bigger and certainly tougher than Fredo.

Second, at that point in the story, when Mike meets Moe, he had not yet nearly established his eventual personal reputation, nor has he restored the Corleone family to their former position of prominence as the leading crimne family in the country. Far from it, in fact.

As Moe says, the perception was that the Corleones were "being chased out of New York by Barzini and the other families" and were perceived as dealing from weakness rather than strength.

And Moe also was bigger than Michael - hell, that's not saying much.....even Kay was bigger than Michael - and, from his NYC backround in a fist fight, very likely tougher

So I don't see that Moe would have necessarily had any fear of touching Michael, either.

Of course, Michael never would've been in any kind of position where Moe had an opportunity or a reason to slap him around, but in the ridiculously impossible event that he was, I don't think Moe would have had any problem in doing so, for exactly the same reasons that he had no problem smacking Fredo.

If we re-examine the situation here, we find that Fredo was in Las Vegas to work directly under Moe while learning the hotel/casino business.

we know that Moe was "headstrong" - his good friend and sometimes mentor Hyman Roth tells us so in GF II, and I can imagine the short-tempered Mr. Greene smacking the hotel chef for putting too many (or not enough, if you prefer) bluberries in the muffins, the casino pit boss for allowing a high-roller to make an ultimately winning bet larger than a table maximum allowed for, the hotel dance director for choreographing a number in which the girls did not display enough cleavage, or the casino credit manager for extending too much credit to a player who succumbs to his mound of debt to the casino and dives underground and disappears.

So even if Fredo had been taking care of business rather than "taking care of business" he might not have been able to avoid Moe Greene's thumb (and other four fingers as well ) forever.

In fact, given Fredo's overall stupidity, if you buy into the idea that a good face slapping was one of Moe's M.O.'s, then Fredo's gaining this particular kind of "hands-on" experience in the hotel/casino business was almost inevitable.

My original question, following your suggestion that Fredo "allowed" himself to be slapped around, was to say that he should "act lke a man"

Then the rest of your post was all Michael, Michael, Michael.

Whatever Fredo did, he did.

Moe, justifiablly or not, then proceeded to slap him around.

What was Fredo supposed to do about it?
