I make a vast exception in the case of the Cross of Christ. Think about it: Paul said something like this at a time when a cross meant something similar to the electric chair:
See with what large letters I am writing to you with my own hand. It is those who want to make a good showing in the flesh who would force you to be circumcised, and only in order that they may not be persecuted for the cross of Christ. For even those who are circumcised do not themselves keep the law, but they desire to have you circumcised that they may boast in your flesh. But far be it from me to boast except in the cross of our Lord Jesus Christ, by which the world has been crucified to me, and I to the world. Gal 6:11-14
For me it's also a poignant reminder that the Mormons reject the display of the Cross because it's a shame and a picture of suffering.
Yet "
For Christ did not send me to baptize but to preach the gospel, and not with words of eloquent wisdom, lest the cross of Christ be emptied of its power. For the word of the cross is folly to those who are perishing, but to us who are being saved it is the power of God." 1 Cor 1:17-18
I think it's critical that we not make it some cheerleading rally point, no. We must become familiar with the depth of suffering the God of the Universe underwent for us. Otherwise it's just a happy symbol. And it could become trite if poorly treated.
But it's a symbol, and a symbol that deserves to be used -- when it can be used to remind us of the greatness of His humility, the vast redemption we've received through His suffering.
