I can only speak for myself...
I bought a lot of raffle tickets  for Don's tank back in August. I had absolutely no need for another  tank, and at the time I thought, if I win this, I will likely sell it at  a (far) below market price (hopefully to a MASC member). However, the  primary reason I bought them was to kick in money for the club's  fundraise. In this case, for Don's family, it was a particularly dear  cause to me.
I haven't had many opportunities to attend meetings  because I have a lot of kids. I really have not needed any supplies or  equipment, however I likely would have kicked in raffle ticket buys to  support MASC fundraises (and likely would have sold for "profit"  whatever I won). I say "profit" with quotes because...the hobby costs  significant money...personally I don't see any margin I make on selling  anything (no matter its cost to me) as "profitable".
Since now  that I understand that many (maybe half?) of the group would view this  as insulting, I probably will never buy tickets in a raffle. I don't  want to insult the community.
All that said, my bigger concern  would be on behalf of MASC's fundraising. If a large percentage of the  club is in my shoes (whether that is 1/10th...1/3rd...half...I have no  clue)...then I would be afraid that the club's fundraise from raffle  draws could substantially decline if this activity is frowned upon.  Further, it could be a catch 22 for the vendors...the bigger that MASC fundraises  are or become, the more opportunity vendors have to get "hype/word of mouth"  marketing by donating something big for a raffle...conversely, if the  fundraises are small or start dwindling, they wouldn't get much benefit from participating  and likely may do smaller or token donations. As a small business  owner, personally I would want to donate product for fundraisers where  wide appeal is most possible, and couldn't care less if raffle winners  flipped the product I gave to a club as soon as they won...but that's  just me, not sayin' that our vendors would feel this way.
Lastly I would just suggest that, if this activity is  officially frowned upon, there should be a MASC rule stating that this  activity may draw a club ban (or whatever penalty is decided...raffle participation etc). Either it is officially OK or officially  not OK, so as to avoid community anger on how one side or the other  interprets.
Again, just my own point of view to throw out there...I'm good with whatever community-wide decision is (and also am glad to know it so I don't offend now or in the future)...
