I don't ever recall Ellen pushing her sexuality. She tried to keep it private and was outed. Being a very honest person she did not deny it. She tried to down play it, her exact quote being, "Yes I am Lebanese." She is not outspoken about it. The firestorms that have resulted in show cancellations have not been instigated by Ellen.
Ellen is an extremely kind, generous, honest and loving person, all very Christian values. However, to many Christians, she is GAY and nothing else. I wouldn't say that I am pro gay, but I do have a problem when people that I know lie, cheat, steal, philander, demonstrate hatred and bigotry, all sins, get very demonstrative about Ellen's sexuality being a sin, rather than learning from her strengths.
I will allow God to deal with her sensuality. Meanwhile, I will try to learn kindness, generosity, honesty and respect for my fellow beings from her. If I learn from Ellen's strengths, then I will be the better Christian for it.
Ellen's first sitcom "Ellen" was initially quite successful until the character she played "came out." She may have been "outed" before that, I don't recall. Anyway, the show quickly lost ratings and Ellen went on several talkshows, notably Oprah, in which she discussed her lifestyle and her show's demise. I would charactarize that as 'pushing' her lifestyle choices. Then there was the very publicized relationship with Portia De Rossi.
It was a little hard to ignore.
You also just described a Mr. Jerry Sandusky, former employee and same-sex rapist of little boys of PSU.
Well, isn't that special. Like a lot of head-in-the-sand "Christians," you don't seem to care how impressionable children and teens will be influenced by a major retailer's public endorsement of someone who practices distorted behavior.
