写We don't agree to your opinion?可以吗

agree with +人
agree to +建议

也可以，但是最好写成We can't agree to your opinion？

先说一下agree的多种用法吧
1.agree with sb/agree with what one says同意
2.agree with 与.一致,适合
3.agree to +建议、意见、提议、观念等
4.agree on 达成一致的协议（注：主语是协议的双方）（例子：China and France agreed on the building of a car factory.中国与法国对汽车厂建筑达成一致协议）
所以agree to 后面是opinion 是可以的.多记住一些一个单词的不同用法会让你在英语上游刃在余的.
