Often believers, especially new converts, has face persecution from their own people for standing for what they believe is the truth.

Peter's answer to this problem:

Now who is there to harm you if you are zealous for what is good?

But even if you should suffer for righteousness' sake, you will be blessed.

• Have no fear of them, nor be troubled, but in your hearts honor Christ the Lord as holy,
• always being prepared to make a defense to anyone who asks you for a reason for the hope that is in you;
• yet do it with gentleness and respect, having a good conscience, so that, when you are slandered, those who revile your good behavior in Christ may be put to shame.

For it is better to suffer for doing good, if that should be God's will, than for doing evil. For Christ also suffered once for sins, the righteous for the unrighteous, that he might bring us to God, being put to death in the flesh but made alive in the spirit.

-- 1 Peter 3:13-18 (ESV)

Usually actions speaks louder than words any ways. If your adversary do not believe your words, they might believe your actions. You might feel that you have a very good reason to respond aggressively or even take revenge for the unfair treatment you might have received, but it is better to "do good" as Peter said.

For example:

But if when you do good and suffer for it you endure, this is a gracious thing in the sight of God. For to this you have been called, because Christ also suffered for you, leaving you an example, so that you might follow in his steps.

He committed no sin, neither was deceit found in his mouth. When he was reviled, he did not revile in return; when he suffered, he did not threaten, but continued entrusting himself to Him Who judges justly.

-- 1 Peter 2:20-23 (ESV)

If you are in a scary position in the face of persecution for speaking the truth, Paul reminds us:

As it is written,

For your sake we are being put to death all day long, we are considered as sheep to be slaughtered.

No, in all these things we are more than conquerors through Him Who loved us.

For I am convinced that neither death, nor life, nor angels, nor rulers, nor things present, nor things to come, nor powers, nor height, nor depth, nor any other created thing will be able to separate us from the love of God that is in Christ Jesus our Lord.

-- Romans 8:36-39 (REV)

I know it is painful, lonely and uncomfortable, but...

Blessed be the God and Father of our Lord Jesus Christ, the Father of mercies and God of all comfort, Who comforts us in all our affliction, so that we may be able to comfort those who are in any affliction, with the comfort with which we ourselves are comforted by God. For as we share abundantly in Christ’s sufferings, so through Christ we share abundantly in comfort too.

• If we are afflicted, it is for your comfort and salvation; and
• if we are comforted, it is for your comfort, which you experience when you patiently endure the same sufferings that we suffer.

Our hope for you is unshaken, for we know that as you share in our sufferings, you will also share in our comfort. -- 2 Corinthians 1:3-7 (ESV)

Endure the afflictions, because that is part of growth. For example, all small children grow through pain, by falling, bumping their heads, scratch themselves and so forth, until they learned to walk. Likewise, pain causes us to speed up our spiritual growth by build a stronger character which is more like Christ.
