Is it bad that my friend tells blond jokes and blond?

It depends. While blond jokes can be funny, they can also be offensive and perpetuate stereotypes. It's important to be mindful of the feelings of others and avoid jokes that could be hurtful. If your friend is making blond jokes in a lighthearted way and not intending to be offensive, then it may not be a big deal. However, if your friend is making these jokes in a derogatory or hurtful way, then it may be time to have a conversation with them about the impact of their words. It's important to remember that humor is subjective and what one person finds funny, another may find offensive. It's always best to err on the side of caution and avoid jokes that could potentially hurt someone's feelings.
