I wouldn't destroy it. I don't see how that could be beneficial to anyone; at most it will just anger the followers of that religion (which is really bad for dawah purposes) and at the least, noone will notice so noone will care - I will have exerted energy and wasted time over something completely insignificant which carried zero benefit to anyone on the planet.
Either way, it wouldn't fit in with giving dawah (one outcome does the exact opposite and pushes them further from Islam; the other doesn't bring them any closer to it...so why bother? I know the Prophet Ibrahim did something similar but there was actually a point being made - in this example, it's just: ''No one is looking...quick let's smash it to bits!''
