I don't think that's really up to you to say, is it? Peter quoted Joel to prove why the people gathered were seeing what they were seeing...in other words...why the Apostles were not drunk.
But others mocking said, “They are filled with new wine.”
But Peter, standing with the eleven, lifted up his voice and addressed them: “Men of Judea and all who dwell in Jerusalem, let this be known to you, and give ear to my words. For these people are not drunk, as you suppose, since it is only the third hour of the day. But this is what was uttered through the prophet Joel: -Acts 2:13–16
You will notice that Peter uses Joel to answer specifically to the charge that they were behaving strangely. As for it "being fulfilled" then...I think it's clear that Peter is saying that it's fulfillment is beginning then. When the Spirit fell, he began working in the people of God in miraculous ways. And indeed, scripture bears testiment to such wonders. While the ultimate fulfillment is, of course, yet to come, we can even say that there have even been signs in the heavens; we've had blood moons and solar eclipses...in fact, a solar eclipse occured when Christ died on the cross.
So...how can we say that Joel is NOT being fulfilled? That it did not start at that moment when the Disciples were infilled with the Spirit and began speaking the languages of everyone gathered there. That was Peter's meaning when he used Joel...."look...it is not wine, it is the Spirit, as promised in the last days!".
Yes, it would be correct to say I think Dispensationalism is, as a system, in error. However, you are very wrong to say I dislike the Rapture. I long for the Rapture. I just view it as occuring at a different time then you, and probably under different circumstances. But, I still view it as a very biblical teaching...one that calls on us to see it as our blessed hope.
Just because you keep repeating that, doesn't make it true, sorry. When Joel speaks about "pouring out my Spirit"....he is talking about the New Covenant...the one where the Holy Spirit is given to indwell. That...is the Church. Any Jew who receives the Holy Spirit in this Age, has become part of the Church. One people in Christ.
While I am pleasently surprised you have used scripture to try and prove your point, I still disagree, sorry. Peter uses Joel 2:28-32 to apply to this age, not the previous section, not what comes after it. And, if you read the whole Chapter 2, you can see why. It's almost like the prophet vision changes focus, from near, to far, then to near again. He goes from seemingly talking to National Israel, to a time in the future, before the 'great and awesome day of the Lord'..and then back to the Nation at hand again. And what helps us mark it out as different is how the Spirit will be poured out. In the OT, the Spirit didn't work through all people. Through the prophets, and various 'chosen' ones, yes, but most...no. It is only in the Church age, after Christ left, that he sent the promised 'Helper'...to "all flesh". That marks it rather specifically. And Peter confirms it by quoting it under the Spirit's influence.
So...no. No giant locuts, and not for National Israel...for the Church.
