As per what they call themselves, but to be of Christ is to follow his teachings of love. This is what they are, as per Matthew 25:40-45:
40 “The King will reply, ‘Truly I tell you, whatever you did for one of the least of these brothers and sisters of mine, you did for me.’
41 “Then he will say to those on his left, ‘Depart from me, you who are cursed, into the eternal fire prepared for the devil and his angels. 42 For I was hungry and you gave me nothing to eat, I was thirsty and you gave me nothing to drink, 43 I was a stranger and you did not invite me in, I needed clothes and you did not clothe me, I was sick and in prison and you did not look after me.’
44 “They also will answer, ‘Lord, when did we see you hungry or thirsty or a stranger or needing clothes or sick or in prison, and did not help you?’
45 “He will reply, ‘Truly I tell you, whatever you did not do for one of the least of these, you did not do for me.’
A person whom Christ calls out as "you who are cursed, into the eternal fire prepared for the devil and his angels" cannot be called in good faith (hardy har) a true Christian, like a true Scotsman must at least be from Scotland.
The callous fools cheering for 500k deportations of people back to war-torn lands full of strife are no Christians, my friend, no matter what they say.

Hypocrisy is one of the 19 vices of the soul, all of which act in opposition to love, the Great(est) Command(ment).
