I think spanish should be banned
Why do you feel like this? Are you able to speak Spanish?
It's my mother tongue, I speak spanish 100% fluently.
You shouldn't discriminate against people based on their language. Maybe you can develop an appreciation for Spanish since it's your language. You might need to know it for something later and you will be glad you kept your language skills.
You know, I think you're right. I should try to be more openminded about different languages.
That's good! I'm glad you've learned to be a bit more accepting of others. You'll probably be a lot happier if you're able to continue to be openminded.
