no.

no.
I'm not a crusader, nor am I a paragon of morality. I would suggest to you, that such personally held traits are dangerous.
As an example, the dongle joke had nothing to do with sexism.
I am not trying to shame you but have you ever been around groups of women as they work or play? Off color jokes are typical of the species homo sapiens in 2014.
The real sexists are the people - including the distinguished Miss Richards who initially reported the joke - who presume that women are such delicate little flowers that they can't exist in an environment for adults, where people occasionally make jokes that are unsuitable for kindergarten kids.
(i.e. I quite agree with you!)
At least you also said what you really mean, that the sexism is problematic, but far too often I have seen people pretend that their issue with a offensive/bigoted/problematic joke is that it is not funny or cliche^. Let's be honest here, that is not actually what bothers people. We only hear those objections when there is something else wrong with the joke; nobody objects to non-offensive unfunny jokes. Groan perhaps, but not object.
^ Usually this manifests as something like "it's not even that it is offensive, the joke is just _lazy_"
I like dick jokes as much as the next person, but they have to be funny. It's not as "shocking" as you think. It's cliche.
Right, but that is not because they are unimaginative or cliched (evidenced by you being able to wade through mountains of bad puns). It is because they are scatological or sexist.
