There are many today who seek the tribulation period and feel the need to be judged and for "purification" they say. There seems to be an intrinsic need for receiving the Lord's unmitigated wrath during His coming judgment against human intransigence in spite of the truth about the matter as the scriptures tell. This is a strange thing indeed.
There will be a place for them if they are living at the time of the beginning of the period and in they will go. This is a Biblical fact. There are even some who claim super "elite" status and that they will somehow be made into invincible perfected beings for the purpose of establishing the Lord's coming millennial kingdom themselves before He gets involved.
There are some who claim "protected" status by billing themselves as the 144,000 sealed mortal Israelites, or the believing part of national Israel who will flee into the Jordanian wilderness, and even the two prophets who will stand before the Lord in Jerusalem. These protections are limited and specific; and only if one is an ethnic Israelite. And there are even some who look forward to martyrdom and having their heads removed.
All of these argue themselves into the events of the tribulation with much vigor and attempt to convince others to go with them by supporting their views with scripture by aberrant teaching. I say let them go. Do not fight the issue with them. The Lord will execute His coming judgment against unbelief and related actions in spite of what humans think. He will not change His schedule.

WARNING: The believer must be ready for the Lord's "harpazo" action to immortalize the Church and not to be found refuting His promise. There are only two resurrections to immortality scheduled during the tribulation period .... the Lord's two prophets and the tribulation martyrs. No others are described. The gatherings of a few surviving mortals at the end of the tribulation period as noted in Matthew 24:29-31 and 25:31-46 are not resurrections.
