Kyousuke did his long speech trying to get through to his father and have him accept Kirino's hobby, even resorting to strong means like grabbing his father's collar and shouting.
He didn't get anywhere, however. The only thing he reached was that his father was getting annoyed by Kyousuke trying to convince him otherwise. His father's bad opinion about anime in general (and eroge especially) was already set in stone, and he didn't want to change it. He didn't concede the tiniest bit and never admitted that anime by itself wouldn't be all that bad or anything.
Because the discussion with Kyousuke was getting on his nerves and he didn't want to change his mind anyway, he brought up the R18 rating to stop any further discussion dead in its tracks.
Since his father was so unrelenting and unmoved by his speech, this left Kyousuke the only option of confessing that it was all his stuff. This only worked for the sole reason that his father already didn't like Kyousuke and had a very low opinion of him. Kyousuke playing eroge (in his fathers opinion totally depraved) fitted exactly in his father's preconceived image of Kyousuke being a bad boy with nasty vices and whatnot, so he instantly believed it without giving it any further consideration. Him hitting Kyousuke was his father's way of saying, "I'm finished with you, once and for all!"

I should say the same to you. Where in the anime does it say or show that their father still did not tolerate Kirino's anime?

His father was unwavered in removing Kirino's eroge. Eroge makes up the bulk of her collection, so removing only the eroge is the same as trashing her entire hobby.

Spoiler for anime subs:

*after Kyousuke grabs his father's collar, threating to beat him down*

Father: "I understand what you're trying to say. I will take back saying that they're worthless. I will let Kirino keep her hobby."

Kyosuke: "Really?"

Father: "But this is different." *picks up eroge* "I can't allow her to have something so indecent. It's not a question of good or bad. What do you think this symbol means?" *camera zooms in on R-18 rating*

Kyosuke (thinking): "So it came down to this after all. This is where Dad is completely right. I do have a plan for this, but..."

Father (while getting up): "I'm going to Kirino's room. She will throw away these at the least."

His father explicitly states that he's only getting rid of the eroge. Whether he changes his mind, or whether he was lying to Kyosuke is another topic for discussion, but it doesn't change the fact that he said he accepted Kirino's hobby.
