Welcome LostReality! 
You will find some here who agree with you, and you will find others with a different viewpoint.
We don't really know anything about Jen's "morals" other than her stating she has them.
Walking around with more than half her ass hanging out, stating she and Nick were "making out", lying, and eating food when SHE herself CHOSE to go on slop for 30 days in order to WIN a POV competition, are not traits that I see as "moral."
We only know what we see....Jen has chosen to put herself on this show and present herself in a certain manner. (as have all of the HG's) That is how she is choosing to play the game. By putting herself out there, she has in effect put her family out there too. None of us knows how Jen's father would react to being in a house with his daughter and a bunch of strangers. To state otherwise, is unrealistic.
Jen is a strong player when it comes to the competitions. Any smart player, when given the opportunity, should try to get her evicted.
Isn't that the game??
Thank you and good to be here

I agree and dissagree with some of the remarks you pointed out.
Bathing suits that Jen wears can be seen on any beach in america and elsewhere. Her style in beach wear don't count for bad morals. (wont mention Eric wearing her bathing suits and the mad streakers).
Making out with Nick or any other male. Does not count as bad morals, if it did there would be no children to teach morals too. I think everyone makes out at some point in life. I hope anyways

As far as the PoV and giving up something or taking something on in order to win, just shows determination and eating slop for 30 days don't again count as bad morals either. It rather to me shows great determination and that she is willing to make a sacrifice for what she wants or believes in. So actually IMO only.. I see it as something admiriable.
As for putting herself on the show the same goes for Dani only she got Daddy to protect her, and I honestly again IMO think it's totally unfair to put a father daughter vs Ex friends and Ex boyfriends up. Naturally blood is thicker than water.
As far as lying I see that as part of the game, and she's done very little in the way of lying but for an example she says something and allows others to come to their own conclusions such as the remark about Eric saying that he'd not be outsmarted by a 21 yr old. He was talking about Dani not Jess, but her saying it to Jess allowed jess to fall into what she wanted her to think at the time. The show isn't bassed on honesty.
100% agree not everyone will agree with everyone elses opinions and as fans together that's what makes this more interesting, just as how they all react diffrently on the show makes for an more interesting show.
