This group is the one where the poster came from.
It’s on this page a aborted fetus at the end of bloody rainbow hands.
This seems to be be a anti abortion group that is making a fairly agressive presence in Seattle.

Indeed, God has used sinful men to flood the earth with symbols of His patience and grace. Every time you see a “pride” rainbow, think of the long-suffering mercy of almighty God holding back his coming wrath; allowing you one more breath — one more chance to repent — one more moment to be forgiven and set free. God is showing you mercy right now, beckoning you to turn away from your sin and look upon Him.
Please don’t hate us for telling you the truth. We produced this tract because we love you and know that the “The Lord is not slow about His promise . . . but is patient toward you, not wishing for any to perish but for all to come to repentance” (2 Peter 3:8-9). We were enemies of God once, and it was his grace that saved us and enabled us to follow Him. It would be hateful to withhold this truth from you and rob you of the chance to be washed clean and join us in the Kingdom of God. Today is the day of salvation. The coming judgement of God against sin will not tarry forever.
