Why yes, there are. They are called browsers, which you can use to navigate to "other forums".

As @MJ5150 pointed out, there are rules here, which you (and other users) agreed to.
If the rule at my house is "no drinking", and you drink, I will throw you out. You can ask me to check your id and allow you to drink if you're over 21, but I don't have to agree to do it - it's my house.
It is entirely possible to express oneself adequately without profanity. Challenging sometimes, but quite do-able. And as a user here who is no stranger to profanity, I find the caliber of conversation here is better for its absence.
