1) RNGs used to generate cards are fair but will not argue with you, or anyone else, if you belong to those people I use to define "rigtards" ( rigged poker theorists) because that discussion will still leave anyone of us on the same side. So I think you are wrong on this.

2) You are not forced to go allin: you have the options either to fold preflop or just call BB (and BB is 20% of maximum buyin at those tables). So there is a bit of skill involved (you should know what range of hole cards have >50% equity against another random couple of cards). So I can definitely state you are wrong on this particular opinion.

3) It is related to the previous point: if you have a clue of what to do, and depending on your oppononents skills, playing poker is definitely more convenient than playing any other casino games in which there is a predefined house edge (whose percentage depends on the game). So in some way you may be wrong on this one.

Be aware it is nothing personal at you or anyone else but it's just to share opinions and I'm ready to change mine once I'm proved to be wrong.
