Ugh, the mom and her hatred towards casinos -- please help

[yellowjack]

The background info: My mom's dad has losts millions in gambling. He was a very smart construction contractor but gambled like a madman on horses, roulette, craps, you name it. He didn't go broke but spent almost every weekend gambling. My mom went with him a few times and has a very damaging memory of placing a bet for roulette, only to have another person call back the bet as his own before the wheel was spun. It's haunted her for life, and her perception of casinos and people in casinos. She also has memories being up big playing other casino house games and then losing it all in a single bet.

The situation: When I started playing poker almost a year ago it was alright because it was small stakes. I started going to the casinos when I was of age but never told her. However the bubble kind of burst a few days ago when I won the first tournament I entered for a lot of money. The money is irrelevant, but I wanted to tell her so that -

1) she could stop worrying about me & money
2) i can take my family out to dinner
3) to come clean with her

I told my dad and he's ok with it because he gambled when he was my age and is rid of it. I think I impressed him with my maturity towards "responsibly gambling" (i.e. limits, not playing spontaenously, playing for entertainment?)

I only told her I've been there 3 times, which is a lie. I've been about 10 times this year. Just today we discussed how she didn't want me to go to the casinos regularly for entertainment. I guess my dad's advice was bad to put it lightly.

I don't know how to paraphrase everything that my mom has said about me playing but the list below is what I recall. We've discussed this very openly and both my mom and I are good at not getting directly angry at each other, but trying to explain our rationale in as calm a way as possible:

<ul type="square">[*]the people i'm playing with are addicted[*]the fact that i used to restrict my play to online tables and now am going to the casino is a sign of addiction[*]me not agreeing to never go to the casino again is a sign of me being addicted[*]young people like myself (im 19) have better things to do for entertainment[*]it is scary for her that im not intimidated in a casino, nor by the people i play with[*]casinos are detrimental for society, so i shouldnt be there[*]there is a high risk of me getting robbed of my money at the table, in the casino somewhere, in the parking lot, or anywhere on the drive home[/list]
In case it is not obvious, she doesn't care for any sort of money &amp; time management I have planned. She doesn't want me there, period. I see why though, it's not about that. It's me being physically in the casino, or in her eyes, hell's gate.

I have tried to think logically about each of her points. The one that strikes me is me being addicted if I cannot agree to never go to the casino again. This is true (that I don't want to agree to this), so I suppose it is true that I'm already addicted. My rationale (to myself, earlier) was that the tables are easier live and for higher stakes, but I'm beginning to have my doubts.

As for a few of her other points, I believe she is being paranoid with robbery and that people are not that unpleasant to be "terrified of". I suppose I should have better things to do but I feel I am good at hold'em. I like doing what I'm good at it.

She's obviously correct in casinos being detrimental. So what do I do here? What are your thoughts on my perspective and my mom's? Is there anything I could do for us to go onto common grounds or will there be no peace? If you have a similar issue with your rents, please tell me. PM me if you're uncomfortable and I'll gladly take any constructive advice/feedback.
